Laser Emits Pure Light

Authors: George Rajna
Comments: 67 Pages.

Researchers have developed a compact laser that emits light with extreme spectral purity that doesn't change in response to environmental conditions. [40] A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg/Germany presents evidence of the amplification of optical phonons in a solid by intense terahertz laser pulses. [39] Femtosecond lasers are capable of processing any solid material with high quality and high precision using their ultrafast and ultra-intense characteristics. [38]

Algorithm Reduce Electromagnetic Noise

Authors: George Rajna
Comments: 79 Pages.

In order to design noiseless electromagnetic (EM) devices, it is necessary to clarify the mechanism behind EM noise and theoretical calculations and computer simulations are performed for prediction assessment of devices. [46] Transparent electronics are the future, according to researchers including José A. Flores-Livas and Miglė Graužinytė from the research group headed by Stefan Goedecker, Professor of Computational Physics at the University of Basel. [45] For the first time ever, an international team of researchers imaged the microscopic state of negative capacitance. [44] One of the leading candidates, spintronics, is based on the idea of carrying information via the spin of electrons. [43]

Quantum Fridge Minibar

Authors: George Rajna
Comments: 49 Pages.

Researchers in Singapore have built a refrigerator that's just three atoms big. This quantum fridge won't keep your drinks cold, but it's cool proof of physics operating at the smallest scales. [35] Researchers have created a new testing ground for quantum systems in which they can literally turn certain particle interactions on and off, potentially paving the way for advances in spintronics. [34] In 2017, University of Utah physicist Valy Vardeny called perovskite a "miracle material" for an emerging field of next-generation electronics, called spintronics, and he's standing by that assertion. [33] Scientists at Tokyo Institute of Technology proposed new quasi-1-D materials for potential spintronic applications, an upcoming technology that exploits the spin of electrons. [32] They do this by using "excitons," electrically neutral quasiparticles that exist in insulators, semiconductors and in some liquids. [31]

Authors: George Rajna
Comments: 95 Pages.

Finding a material which behaves as a superconductor at room temperature would be a scientific breakthrough of incredible conceptual and technological importance.

Safeguards for Sensitive Information

Authors: George Rajna
Comments: 96 Pages.

Despite being the most advanced quantum technology, secure encryption of information units based on a method called quantum key distribution (QKD) is currently limited by the channel's capacity to send or share secret bits. [55] An international team of researchers led by ANU is helping to build a safe data superhighway for the highly anticipated quantum internet, which promises a new era of artificial intelligence and ultra-secure communication. [54] For the first time, researchers have succeeded in producing what are known as spin wave overtones. The technology paves the way for increasing the data transmission rate of wireless communication. [53]

Einstein-Classicality Explains Aspect's Experiment and Refutes Bell's Theorem

Authors: Gordon Watson
Comments: 6 Pages.

With Bell's inequality refuted and his error identified [see References], we now explain Aspect's experiment and refute Bell's theorem via what we call Einstein-classicality: the union of true locality (no influence propagates superluminally) and true realism (some beables change interactively). We also remedy many of Aspect's pro-Bell comments; eg, inability to picture in 3-space, hopeless searching, vindicated nonlocality.

Cosmological Acceleration as a Consequence of Quantum de Sitter Symmetry

Authors: Felix M Lev
Comments: 13 Pages.

Physicists usually understand that physics cannot (and should not) explain why $c=3\cdot 10^8m/s$ and $\hbar =1.054\cdot 10^{-34}kg\cdot m^2/s$ because $c$ and $\hbar$ are fundamental physical quantities. At the same time they usually believe that physics should explain the value of the cosmological constant $\Lambda$. We first prove that three fundamental parameters defining transitions from more general theories to less general ones are $(c,\hbar , R)$ where $R$ is the parameter defining contraction from the de Sitter (dS) or anti-de Sitter (AdS) algebra to the Poincare algebra. This parameter is fundamental to the same extent as $c$ and $\hbar$. In particular, a question why $R$ is as is does not arise, and the answer is simply that $R$ has its value because people want to measure distances in meters. On classical level $\Lambda=\pm 3/R^2$ for dS and AdS spaces, respectively. As a consequence of the fact that quantum dS and AdS symmetries are more general than Poincare symmetry, the cosmological constant problem does not arise, $\Lambda$ is necessarily not zero and there is no need to involve dark energy for explaining the cosmological acceleration. Following our previous publications, we consider a system of two free bodies in dS invariant quantum mechanics and show that in semiclassical approximation the dS repulsion is the same as in General Relativity. This result is obtained without using geometry of dS space, metric and connection but simply as a consequence of quantum dS symmetry.

Note on the Golden Mean, Nonlocality in Quantum Mechanics and Fractal Cantorian Spacetime

Authors: Carlos Castro
Comments: 7 Pages.

Given the inverse of the Golden Mean $ \tau^{ -1} = \phi = { 1\over 2} (\sqrt 5 - 1)$, it is known that the continuous fraction expansion of $ \phi^{ -1} = 1 + \phi = \tau$ is $ ( 1, 1, 1, \cdots )$. Integer solutions for the pairs of numbers $ ( d_i, n_i ), i = 1, 2, 3, \cdots $ are found obeying the equation $ ( 1 + \phi)^n = d + \phi^n$. The latter equation was inspired from El Naschie's formulation of fractal Cantorian space time $ {\cal E}_\infty$, and such that it furnishes the continuous fraction expansion of $ ( 1 + \phi )^n ~= ~ (d, d, d, d, \cdots )$, generalizing the original expression for the Golden mean. Hardy showed that is possible to demonstrate nonlocality without using Bell inequalities for two particles prepared in $nonmaximally$ entangled states. The maximal probability of obtaining his nonlocality proof was found to be precisely $\phi^5$. Zheng showed that three-particle nonmaximally entangled states revealed quantum nonlocality without using inequalities, and the maximal probability of obtaining the nonlocality proof was found to be $ 0.25 \sim \phi^3 = 0.236$. Given that the two-parameter $ p, q$ quantum-calculus deformations of the integers $ [ n ]_{ p, q} = F_n $ $coincide$ precisely with the Fibonacci numbers, as a result of Binet's formula when $ p = ( 1 + \phi) = \tau, q = - \phi = - \tau^{ -1} $, we explore further the implications of these results in the quantum entanglement of two-particle spin-$s$ states. We finalize with some remarks on the generalized Binet's formula corresponding to generalized Fibonacci sequences.

Magnetic Quantum Effects in Solids

Authors: George Rajna
Comments: 28 Pages.

Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3-D pyrochlore Heisenberg model. [18] Researchers in the US and Japan say they have observed spin superfluidity and very long distance spin transport in an antiferromagnetic insulator made from graphene for the first time. [17] The first known superconductor in which spin-3/2 quasiparticles form Cooper pairs has been created by physicists in the US and New Zealand. [16] Now a team of researchers from the University of Maryland (UMD) Department of Physics together with collaborators has seen exotic superconductivity that relies on highly unusual electron interactions.

Quantum Computing in Four Spatial Dimensions

Authors: Arturo Tozzi, Muhammad Zubair Ahmad, James F Peters
Comments: 11 Pages.

Relationships among near set theory, shape maps and recent accounts of the Quantum Hall effect pave the way to quantum computations performed in higher dimensions. We illustrate the operational procedure to build a quantum computer able to detect, assess and quantify a fourth spatial dimension. We show how, starting from two-dimensional shapes embedded in a 2D topological charge pump, it is feasible to achieve the corresponding four-dimensional shapes, which encompass a larger amount of information. This novel, relatively straightforward architecture not only permits to increase the amount of available qbits in a fixed volume, but also converges towards a solution to the problem of optical computers, that are not allowed to tackle quantum entanglement through their canonical superposition of electromagnetic waves.

Qfizika Fizikai ÁLLANDÓK EXPONENCIÁLIS Kapcsolata

Authors: Sarkadi Dezső
Comments: 6 Pages.

A több évre visszamenő töprengéseim során sikerült találnom egy olyan dimenziónélküli számot, éspedig a 2/9-hez közelálló, mely a fizikában valószínűleg hasonlóan nagy érdeklődésre számíthat, mint az ismert 1/137 finimszerkezeti állandó. Ezt az új számot Q-val jelölöm, melynek Q0 „névleges” értékét pontosan 2/9-nek választottam. A 90-es években ismertem fel, hogy ennek a számnak az egész-számú hatványaival számos, dimenziónélküli fizikai állandó kisebb-nagyobb pontossággal kifejezhető (pl. elemi részek tömegarányai), többek között a finomszerkezeti állandó is! Nagyon érdekes az a tény, hogy a legfontosabb fizikai állandók SI egységrendszerben szintén kifejezhetők a Q szám egész-számú hatványaival. Ez lehet csak a nagy véletlen, de lehet mögötte akár komolyabb fizikai háttér is. Sarkadi Dezső 2019.01.22

Comments: 43 Pages.

An international research team led by the University of Liverpool and McMaster University has made a significant breakthrough in the search for new states of matter.

[30] Electrons in graphene—an atomically thin, flexible and incredibly strong substance that has captured the imagination of materials scientists and physicists alike—move at the speed of light, and behave like they have no mass. [29] In a series of exciting experiments, Cambridge researchers experienced weightlessness testing graphene's application in space.

Thought Experiment of Schrodinger

Authors: George Rajna
Comments: 36 Pages.

An old thought experiment now appears in a new light. In 1935 Erwin Schrödinger formulated a thought experiment designed to capture the paradoxical nature of quantum physics. [22] ETH physicists have developed a silicon wafer that behaves like a topological insulator when stimulated using ultrasound. They have thereby succeeded in turning an abstract theoretical concept into a macroscopic product. [21] Cheng Chin, professor in the Department of Physics, and his team looked at an experimental setup of tens of thousands of atoms cooled down to near absolute zero. As the system crossed a quantum phase transition, they measured its behavior with an extremely sensitive imaging system. [20]

The Theories of the Graviton, Part Three: The Statistical and Thermodynamic Applications to Gravitonic Mechanics

Authors: Noah MacKay
Comments: 14 Pages. Done with the assistance of Aaron M. Bain and Ashton L. Shope

Gravitons are the quanta of gravity that, if proven to exist, would potentially connect quantum mechanics with gravitation. The third (and supposedly last) part of the Graviton Theory entity focuses on the thermodynamic and statistical applications to the theories that were proposed in Parts One and Two. This analysis will look at gravitonic influences in black holes and during the Big Bang, as well as interacting gravitons in two extreme systems: as a boson gas and as a Bose-Einstein condensate. The analysis will also explore the thermodynamic and statistical influences on the nature and mechanics of gravitons.

Space, Time and Quantum Mechanics: A Process Approach

Authors: Blazej Kot
Comments: 27 Pages. Previously published in Prespacetime Journal, December 2018, Volume 9, Issue 10, pp. 1018-1048

Since the time of Newton, physicists have imagined a background "stage" called space and time (later spacetime) permeating the entire universe. The contents of the world around us are then seen as objects embedded in this background at a defined location, and with a defined size and other properties (color, mass, spin etc.). We refer to this traditional view as the Objects in Space and Time (OST) model. It works very well for picturing classical physics; but once we move into the quantum domain it is no longer of much use. In the quantum realm objects no longer have defined locations at all times, their properties can become entangled and undefined until observed. In this paper, we seek to present an alternative to the OST model in which the "weirdness" of quantum phenomena goes away and is replaced by clarity, obviousness and inescapability. In this model the world is viewed as a network of fundamental processes by which indivisible units called tomas bring each other into and out of existence. We show that this model yields the same equations and predictions as the current OST-based formalism of quantum mechanics. While not contradicting the success of quantum theory, the toma model lets us get rid of the "weirdness" of the quantum world and understand reality at a deeper level than the OST model. We illustrate this by discussing two classic quantum experiments and their interpretations.

Entropy Production in Quantum Systems

Authors: George Rajna
Comments: 36 Pages.

"We studied two systems: a Bose-Einstein condensate with 100,000 atoms confined in a cavity and an optomechanical cavity that confines light between two mirrors," Gabriel Teixeira Landi, a professor at the University of São Paulo's Physics Institute (IF-USP), told. [21] Search engine entropy is thus important not only for the efficiency of search engines and those using them to find relevant information as well as to the success of the companies and other bodies running such systems, but also to those who run websites hoping to be found and visited following a search. [20] "We've experimentally confirmed the connection between information in the classical case and the quantum case," Murch said, "and we're seeing this new effect of information loss." [19] It's well-known that when a quantum system is continuously measured, it freezes, i.e., it stops changing, which is due to a phenomenon called the quantum Zeno effect. [18]

Fixing Dirac Theory's Relativity and Correspondence Errors

Authors: Steven Kenneth Kauffmann
Comments: 11 Pages.

Dirac sought a relativistic quantum free-particle Hamiltonian that imposes space-time symmetry on the Schroedinger equation in configuration representation; he ignored the Lorentz covariance of energy-momentum. Dirac free-particle velocity therefore is momentum-independent, breaching relativity basics. Dirac also made solutions of his equation satisfy the Klein-Gordon equation via requirements imposed on its operators. Dirac particle speed is thereby fixed to the unphysical value of c times the square root of three, and anticommutation requirements prevent four observables, including the components of velocity, from commuting when Planck's constant vanishes, a correspondence-principle breach responsible for Dirac free-particle spontaneous acceleration (zitterbewegung) that diverges in the classical limit. Nonrelativistic Pauli theory contrariwise is physically sensible, and its particle rest-frame action can be extended to become Lorentz invariant. The consequent Lagrangian yields the corresponding closed-form relativistic Hamiltonian when magnetic field is absent, otherwise a successive-approximation regime applies.

Evidence of Superconductivity Near Room Temperature

Authors: George Rajna
Comments: 30 Pages.

Researchers at the George Washington University have taken a major step toward reaching one of the most sought-after goals in physics: room temperature superconductivity. [41] NUS physicists have developed a methodology to control the electromigration of oxygen atoms in the buried interfaces of complex oxide materials for constructing high mobility oxide heterostructures. [40] This electronic super fluidity is a quantum state of matter, so it behaves in a very exotic way that is different from classical physics, Comin says. [39] The Fermi-Hubbard model, which is believed to explain the basis for high-temperature superconductivity, is extremely simple to describe, and yet has so far proven impossible to solve, according to Zwierlein.

More than 100 years ago, Albert Einstein and Wander Johannes de Haas discovered that when they used a magnetic field to flip the magnetic state of an iron bar dangling from a thread, the bar began to rotate. [36] Researchers at the Max Born Institute have now generated directed currents at terahertz (THz) frequencies, much higher than the clock rates of current electronics. [35] Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have developed a simple yet accurate method for finding defects in the latest generation of silicon carbide transistors.

Close-Coupling: Generating Function and Fokker-Planck for Coherent Multilevel Cascades (Quantum Walks)

Authors: Mark Syrkin
Comments: 12 Pages.

Close-coupling in quantum systems induces cascade transitions that are not captured by simple perturbation theories and hence more relevant and complex methods are needed. However, the analytic tractability of the latter is limited to just a few highly stylized models, e.g. equidistant infinite systems. Showing that properly adjusted key modeling parameters enable an extension of analytic solutions across more realistic cases (e.g. non-uniform level spacing and finite and asymmetric boundary conditions) arising in various experimental set-ups. Also demonstrating that the Fokker-Planck approach applied to probability amplitudes rather than to probabilities themselves – the latter being a traditional kinetics approach – produces coarse-grained amplitudes “smoothed” over the fine structure of an exact solution and driven by lower order terms in the generating function. Models and results presented here naturally overlap with algorithms of Quantum Walks related to quantum computing studies.

Intentionally Squashed Quantum Dots

Authors: George Rajna
Comments: 40 Pages.

Intentionally "squashing" colloidal quantum dots during chemical synthesis creates dots capable of stable, "blink-free" light emission that is fully comparable with the light produced by dots made with more complex processes. [29] Researchers successfully integrated the systems—donor atoms and quantum dots. [28] A team of researchers including U of A engineering and physics faculty has developed a new method of detecting single photons, or light particles, using quantum dots. [27]

Heterostructure Interface Superconductors

Authors: George Rajna
Comments: 33 Pages.

NUS physicists have developed a methodology to control the electromigration of oxygen atoms in the buried interfaces of complex oxide materials for constructing high mobility oxide heterostructures. [40] This electronic super fluidity is a quantum state of matter, so it behaves in a very exotic way that is different from classical physics, Comin says. [39] The Fermi-Hubbard model, which is believed to explain the basis for high-temperature superconductivity, is extremely simple to describe, and yet has so far proven impossible to solve, according to Zwierlein.

Feynman Diagrams of the QED Vacuum Polarization

Authors: Richard J. Mathar
Comments: 59 Pages.

The Feynman diagrams of Quantum Electrodynamics are assembled from vertices where three edges meet: an incoming fermion, an outgoing fermion and an interaction line. If all vertices are of degree 3, the graphs are 3-regular (cubic), defining the vacuum polarization diagrams. Cutting an edge -- a fermion line or an interaction line -- generates fairly cubic graphs where two vertices have degree 1. These emerge in the perturbation theory for the Green's function (self energy) and for the effective interaction (polarization). The manuscript plots these graphs for up to 8 internal vertices.

3-D Photonic Topological Insulator

Authors: George Rajna
Comments: 92 Pages.

Physicists have also devised photonic topological insulators, synthetic materials that impart light waves with distinct topological features, allowing light (rather than electric currents) to flow via topological surface states. [53] "This research highlights the cutting-edge research being done at WVU, and we are very excited to see their work appear in the very high-profile journal Nature Communications." [52] By constructing a hybrid device made from two different types of qubit—the fundamental computing element of quantum computers—they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba—a single-celled organism consisting mostly of gelatinous protoplasm—has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers. [50] For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew.

Conversion of Photons from Particles to Linked Waves and Back: a Hypothesis

Authors: Bruce A. Lutgen
Comments: 3 Pages.

In microphysics, how do photons behave like both waves and particles? It is called wave-particle duality. The wave-particle duality inference would appear to be counter intuitive. Are waves really a cluster of particles, as is often stated, yet like the waves that radiate in a disturbed pool of water as is often demonstrated? The answer to wave-particle duality may lie through the following proposed solid torus or possibly ellipsoid ringform field explanation, which is derived in part using classical physics. A solid torus or ellipsoid ringform hypothesis is contrary to string theory and at least to some extent accepted particle physics.

Toward Unification

Authors: Alexandre Furtado Neto
Comments: 14 Pages.

A universe based on a fully deterministic, Euclidean, 4-torus cellular automaton is presented using a constructive approach. Each cell contains one integer number forming bubble-like patterns propagating at the speed of light, interacting and being reissued constantly. The collective behavior of these integers is conjectured to form patterns similar to classical and quantum physics, including the mass spectrum, quantum correlations and relativistic effects. Although essentially non-local, it preserves the non-signaling principle. This flexible model predicts that gravity is not quantized as well as the appearence of an arrow of time. Being a causal theory, it can potentially explain the emergence of the classical world and acroscopic observers.

Quantum Optic Networks Reality

Authors: George Rajna

The ability to precisely control the interactions of light and matter at the nanoscale could help such a network transmit larger amounts of data more quickly and securely than an electrical network. [59] Researchers in Italy have demonstrated the feasibility of quantum communications between high-orbiting global navigation satellites and a ground station, with an exchange at the single photon level over a distance of 20,000km. [58] Living cells, regardless of the type, can be kept around for a long time and because they move constantly, can be photographed repeatedly to create new encryption keys. [57] A new electronic device can developed at the University of Michigan can directly model the behaviors of a synapse, which is a connection between two neurons. [56] "The atom-scale devices we are developing create a new basis for HYPERLINK "https://phys.org/tags/computer/" computer electronics that will be able to run at least 100 times faster or operate at the same speed as today but using 100 times less energy," continued Wolkow. [55] Significant technical and financial issues remain towards building a large, fault-tolerant quantum computer and one is unlikely to be built within the coming decade. [54] Chemists at Friedrich Schiller University in Jena (Germany) have now synthesised a molecule that can perform the function of a computing unit in a quantum computer. [53] The research team developed the first optical microchip to generate, manipulate and detect a particular state of light called squeezed vacuum, which is essential for HYPERLINK "https://phys.org/tags/quantum/" quantum computation.

The Emperor Has No Clothes: A Realist Interpretation of Quantum Mechanics.

Authors: Jean Louis Van Belle
Comments: 158 Pages.

This draft for a book brings all of the ideas in my papers together in one (hopefully) consistent volume. These papers basically explore Dirac's dissatisfaction with the theory he helped to create, as expressed in his very last paper, which was published in 1984 - just before he died. The title of this last paper of this genius had a rather significant title: the Inadequacies of Quantum Field Theory. And this one line may sum it all up: "These rules of renormalization give, surprisingly, excessively good agreement with experiments. Most physicists say that these working rules are, therefore, correct. I feel that is not an adequate reason. Just because the results happen to be in agreement with observation does not prove that one's theory is correct." This book tries to show that there is a viable alternative.

Rovibrational Quantum State

A central objective of chemical and molecular physics is to understand molecules as quantum mechanical systems. [30] After developing a method to control exciton flows at room temperature, EPFL scientists have discovered new properties of these quasiparticles that can lead to more energy-efficient electronic devices. [29] To build tomorrow's quantum computers, some researchers are turning to dark excitons, which are bound pairs of an electron and the absence of an electron called a hole. [27] Concerning the development of quantum memories for the realization of global quantum networks, scientists of the Quantum Dynamics Division led by Professor Gerhard Rempe at the Max Planck Institute of Quantum Optics (MPQ) have now achieved a major breakthrough: they demonstrated the long-lived storage of a photonic qubit on a single atom trapped in an optical resonator. [26] Achieving strong light-matter interaction at the quantum level has always been a central task in quantum physics since the emergence of quantum information and quantum control. [25] Operation at the single-photon level raises the possibility of developing entirely new communication and computing devices, ranging from hardware random number generators to quantum computers. [24] Considerable interest in new single-photon detector technologies has been scaling in this past decade. [23] Engineers develop key mathematical formula for driving quantum experiments. [22] Physicists are developing quantum simulators, to help solve problems that are beyond the reach of conventional computers. [21] Engineers at Australia's University of New South Wales have invented a radical new architecture for quantum computing, based on novel 'flip-flop qubits', that promises to make the large-scale manufacture of quantum chips dramatically cheaper-and easier-than thought possible. [20] A team of researchers from the U.S. and Italy has built a quantum memory device that is approximately 1000 times smaller than similar devices-small enough to install on a chip. [19]

Can a Human Brain be a Quantum Computer?

Authors: Oleg Kupervasser, Roman Yavich
Comments: 8 Pages. presented at World Quantum Physics Congress 10-13 Dec 2018 (WQPC 2018) Stockholm, Sweden

This paper is based on the book (O. Kupervasser, Application of New Cybernetics in Physics, Elsevier, 2017). Human brain has very powerful intellect. Indeed, it seems that its intellectual possibilities are much more than possibilities of usual computers using genetic algorithm and random search (A.S. Potapov, Artificial Intellect and Universal Intelligence, Polytechnics, Saint Petersburg, 2012 (in Russian).). Our brain has also such especial property as consciousness. Some researchers suppose that these properties are a result of special structures of brain. Really, may be our brain is a quantum computer (R. Penrose, The Emperor’s New Mind, Oxford University Press, New York, 1989, R. Penrose, Shadows of the Mind, Oxford University Press, New York, 1994)? We know that a quantum computer is highly parallel device with principally insuperable protection from external observation. A quantum computer can resolve some tasks that are inaccessible for usual computers. However, it can be demonstrated that continuous unstable classical computer has the same properties as a quantum computer (O. Kupervasser, Application of New Cybernetics in Physics, Elsevier, 2017). Moreover, it seems that the main properties of a brain (powerful intellect and consciousness) can be explained by invisible correlation with surround world. Similarly, clock’s gear wheel very accurately operates in spite of absence of any intellect only because the gear wheel is a part of the highly correlated clock. We usually suppose that our world is some random set of low correlated events. However, the world, may be, is some highly correlated device (L. Susskind, J. Lindesay, An Introduction to Black Holes, Information and the String Theory Revolution: The Holographic Universe, World Scientific Publishing Company, 2004). And human beings are its “gear wheels”. It seems that Big Bang theory suppose such point of view. This pure philosophical reasonings can lead to some practical conclusions. We suppose to use instead of usual random search for computers some random number generators which are in complex correlations with surround world. It can give to computers some prototype of the such especial “human intuition”, described above.

Fast, Tiny Controllable Magnetic Bits

In separate papers published this month in the journals Nature Nanotechnology and Advanced Materials, researchers in the group of MIT Professor Geoffrey S.D. Beach and colleagues in California, Germany, Switzerland, and Korea, showed that they can generate stable and fast moving skyrmions in specially formulated layered materials at room temperature, setting world records for size and speed. [53] Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit-meaning how long it can maintain a special state that allows it to represent two logical states simultaneously. [52] By constructing a hybrid device made from two different types of qubit-the fundamental computing element of quantum computers-they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba-a single-celled organism consisting mostly of gelatinous protoplasm-has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers.

[48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices. [47] In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that can repair or heal itself after damage. [46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks.

Quantum Spin Liquid Pathway

With potential roles in quantum computation, high-temperature superconductivity and a range of exotic anyonic states, why quantum spin liquids (QSLs) attract interest is no great mystery. [31] Now, for the first time ever, researchers from Aalto University, Brazilian Center for Research in Physics (CBPF), Technical University of Braunschweig and Nagoya University have produced the superconductor-like quantum spin liquid predicted by Anderson. [30] Electrons in graphene-an atomically thin, flexible and incredibly strong substance that has captured the imagination of materials scientists and physicists alike-move at the speed of light, and behave like they have no mass. [29] In a series of exciting experiments, Cambridge researchers experienced weightlessness testing graphene's application in space. [28] Scientists from ITMO University have developed effective nanoscale light sources based on halide perovskite. [27] Physicists have developed a technique based on optical microscopy that can be used to create images of atoms on the nanoscale. [26] Researchers have designed a new type of laser called a quantum dot ring laser that emits red, orange, and green light. [25] The world of nanosensors may be physically small, but the demand is large and growing, with little sign of slowing. [24] In a joint research project, scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI), the Technische Universität Berlin (TU) and the University of Rostock have managed for the first time to image free nanoparticles in a laboratory experiment using a highintensity laser source. [23] For the first time, researchers have built a nanolaser that uses only a single molecular layer, placed on a thin silicon beam, which operates at room temperature. [22] A team of engineers at Caltech has discovered how to use computer-chip manufacturing technologies to create the kind of reflective materials that make safety vests, running shoes, and road signs appear shiny in the dark.

Hidden Spin for High-Temperature Superconductors

Authors: George Rajna
Comments: 33 Pages.

Now, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have unveiled a clue into the cuprates' unusual properties—and the answer lies within an unexpected source: the electron spin. [40] This electronic super fluidity is a quantum state of matter, so it behaves in a very exotic way that is different from classical physics, Comin says. [39] The Fermi-Hubbard model, which is believed to explain the basis for high-temperature superconductivity, is extremely simple to describe, and yet has so far proven impossible to solve, according to Zwierlein. [38] Researchers at Karlsruhe Institute of Technology (KIT) have carried out high-resolution inelastic X-ray scattering and have found that high uniaxial pressure induces a long-range charge order competing with superconductivity. [37] Scientists mapping out the quantum characteristics of superconductors-materials that conduct electricity with no energy loss-have entered a new regime. [36] Now, in independent studies reported in Science and Nature, scientists from the Department of Energy's SLAC National Accelerator Laboratory and Stanford University report two important advances: They measured collective vibrations of electrons for the first time and showed how collective interactions of the electrons with other factors appear to boost superconductivity. [35] At the Joint Quantum Institute (JQI), a group, led by Jimmy Williams, is working to develop new circuitry that could host such exotic states. [34] The effect appears in compounds of lanthanum and hydrogen squeezed to extremely high pressures. [33] University of Wisconsin-Madison engineers have added a new dimension to our understanding of why straining a particular group of materials, called Ruddlesden-Popper oxides, tampers with their superconducting properties. [32] Nuclear techniques have played an important role in determining the crystal structure of a rare type of intermetallic alloy that exhibits superconductivity. [31]

Quantum Computer for Quantum Chemistry

Authors: George Rajna
Comments: 61 Pages.

Among many important and fundamental issues in science, solving the Schroedinger equation (SE) of atoms and molecules is one of the ultimate goals in chemistry, physics and their related fields. [36] The standard approach to building a quantum computer with majoranas as building blocks is to convert them into qubits. However, a promising application of quantum computing-quantum chemistry-would require these qubits to be converted again into so-called fermions. [35] Scientists have shown how an optical chip can simulate the motion of atoms within molecules at the quantum level, which could lead to better ways of creating chemicals for use as pharmaceuticals. [34] Chinese scientists Xianmin Jin and his colleagues from Shanghai Jiao Tong University have successfully fabricated the largest-scaled quantum chip and demonstrated the first two-dimensional quantum walks of single photons in real spatial space, which may provide a powerful platform to boost analog quantum computing for quantum supremacy. [33] To address this technology gap, a team of engineers from the National University of Singapore (NUS) has developed an innovative microchip, named BATLESS, that can continue to operate even when the battery runs out of energy. [32] Stanford researchers have developed a water-based battery that could provide a cheap way to store wind or solar energy generated when the sun is shining and wind is blowing so it can be fed back into the electric grid and be redistributed when demand is high. [31] Researchers at AMOLF and the University of Texas have circumvented this problem with a vibrating glass ring that interacts with light. They thus created a microscale circulator that directionally routes light on an optical chip without using magnets. [30] Researchers have discovered three distinct variants of magnetic domain walls in the helimagnet iron germanium (FeGe). [29]

[25] Following three years of extensive research, Hebrew University of Jerusalem (HU) physicist Dr. Uriel Levy and his team have created technology that will enable computers and all optic communication devices to run 100 times faster through terahertz microchips. [24] When the energy efficiency of electronics poses a challenge, magnetic materials may have a solution. [23]

Ultrathin Digital Camera

Authors: George Rajna
Comments: 88 Pages.

The ultrathin digital camera offers a wide field of view and high resolution in a slimmer body compared to existing imaging systems. [50] The special feature of the Kiel system is its extremely high temporal resolution of 13 femtoseconds. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices. [47] In a recent study, materials scientists Guojin Liang and his coworkers at the Department of Materials Science and Engineering, City University of Hong Kong, have developed a self-healing, electroluminescent (EL) device that can repair or heal itself after damage. [46] A team of researchers based at The University of Manchester have found a low cost method for producing graphene printed electronics, which significantly speeds up and reduces the cost of conductive graphene inks. [45] Graphene-based computer components that can deal in terahertz "could be used, not in a normal Macintosh or PC, but perhaps in very advanced computers with high processing rates," Ozaki says. This 2-D material could also be used to make extremely high-speed nanodevices, he adds. [44] Printed electronics use standard printing techniques to manufacture electronic devices on different substrates like glass, plastic films, and paper. [43] A tiny laser comprising an array of nanoscale semiconductor cylinders (see image) has been made by an all-A*STAR team. [42] A new instrument lets researchers use multiple laser beams and a microscope to trap and move cells and then analyze them in real-time with a sensitive analysis technique known as Raman spectroscopy.

Lifetime of Graphene Qubits

Authors: George Rajna
Comments: 92 Pages.

Researchers from MIT and elsewhere have recorded, for the first time, the "temporal coherence" of a graphene qubit-meaning how long it can maintain a special state that allows it to represent two logical states simultaneously. [52] By constructing a hybrid device made from two different types of qubit-the fundamental computing element of quantum computers-they have created a device that can be quickly initialized and read out, and that simultaneously maintains high control fidelity. [51] Researchers have demonstrated that an amoeba-a single-celled organism consisting mostly of gelatinous protoplasm-has unique computing abilities that may one day offer a competitive alternative to the methods used by conventional computers. [50] For the first time, researchers have used tiny gears made of germanium to generate a vortex of twisted light that turns around its axis of travel much like a corkscrew. [49] Physical systems with discrete energy levels are ubiquitous in nature and form fundamental building blocks of quantum technology. [48] In a similar vein, scientists are working to create twisting helical electromagnetic waves whose curvature allows more accurate imaging of the magnetic properties of different materials at the atomic level and could possibly lead to the development of future devices.
