Common Description of Quantum Electromagnetism and Relativistic Gravitation

Authors: Jérémy Kerneis
Comments: 16 Pages.

We use 3 equations as postulates: Pem referring to electromagnetism, Pgrav referring to gravity, and Pqm referring to quantum mechanic and defining the wave function. Combining Pem with "Sommerfeld's quantum rules" corresponds to the original quantum theory of Hydrogen, which produces the correct relativistic energy levels of atoms (Sommerfeld's and Dirac's theories of matter produces the same energy levels, and Schrodinger's theory produces the approximation of those energy levels). Pqm implies that the wave function is solution of both Schrodinger's and Klein-Gordon's equations in the non interacting case while, in the interacting case it implies "Sommerfeld's quantum rules": Pem and Pqm then produce the correct relativistic energy levels of atoms (the same as Dirac's energy levels). We check that the required degeneracy is justified by pure deduction, without any other assumption (Schrodinger's theory only justifies one half of the degeneracy). We observe the connection between Pqm, Quantum Field Theories and tunnel effect. From Pgrav we deduce an equation of motion very similar to general relativity (with accuracy 10^{-6} at the surface of the Sun), our postulate being explicitly an approximation. First of all, we discuss classical Kepler problems (Newtonian motion of the Earth around the Sun), explain the link between Kelpler's law of periods (1619) and Plank's law (1900) and observe the links between all historical models of atoms (Bohr, Sommerfeld, Pauli, Schrodinger, Dirac, Fock).

On the Trouble With Physics

Authors: John Smith
Comments: 19 Pages.

Since the time of the ancient Greeks, the world has been under the sway of the philosophy of atomism, which holds that the parts are prior to the whole, and so that the world is an empty receptacle in which material objects are placed like furniture in an empty room. This philosophy however contradicts the General Theory of Relativity according to which the fundamental condition of the universe involves no space and time and therefore no matter, and has numerous undesirable consequences. It is argued here that the alternative conception -that the whole is prior to the parts, and that space disrupts light rather than the other way around- coheres with theory and with observation, and that it is supported by mathematical principles by reference to which several problems of physics can be solved.

Quantum Gravity Without Additional Theory: Compatibility of Schwarzschild Metric and Quantum Mechanics

Authors: René Friedrich
Comments: Pages. An updated version of this paper may be found at viXra:2007.0107

General relativity and quantum mechanics both have been confirmed by experiments. In order to unify them, a new theory of quantum gravity is searched, but without success. In the following it will be shown that quantum gravity does not require any kind of new theory, and in particular that Schwarzschild metric and quantum mechanics are not contradicting each other, but fitting together harmoniously. The problem is that our current perception of spacetime is based on 3 wrong assumptions which are not complying with general relativity and obstructing our view to the solution. The following 3 corrections are following directly from the two postulates of special relativity and from Schwarzschild metric: 1. Spacetime is no quantizable continuous manifold. 2. For the solution of fundamental problems of physics about time, we must refer to the fundamental parameter of proper time instead of coordinate time. 3. Gravitation may be represented by the Schwarzschild metric not only as the curved spacetime, but alternatively also as gravitational time dilation in absolute, uncurved space. From these 3 insights are following the 7 basic characteristics of quantum gravity. The result: Gravity acts within quantum mechanics in the form of gravitational time dilation.

Pre Octonionic to Octonionic Gravity and Could Kinetic Energy be Larger Than Potential Energy Before Inflation?

Authors: Andrew Beckwith
Comments: 16 Pages.

We look at early universe space-time which is characterized by a transition from Pre Planckian to Planckian space-time. In doing so we also invoke the geometry of Octonionic non-commutative structure and when it breaks down. Doing so is also equivalent to a speculation given earlier by the author as to the kinetic energy of Pre Planckian space-time being significantly larger than the Potential energy, which is the opposite of what happens after the onset of Inflation, with the assumption as to how this is justified given in a (Pre Planckian) Hubble Parameter set as of Eq. (16), and we close with a comparison of this proposal with string cosmology, as represented in the 2nd reference in this paper.

Using Barbour's Ephemeris Time, and Padmanabhan's Inflaton Value ,plus Will’s Massive Graviton Velocity to Isolate Rest Energy of Massive Graviton as Compared to Racetrack Inflation Results of Graviton Physics and Modified Wheeler De Witt Results of wo

Authors: Andrew Beckwith
Comments: 27 Pages.

The idea is to identify via ephemeris time as given by Barbour and an inflaton field as given by Padmanabhan, for scale factor proportional to time to the alpha power and a velocity given by Will for massive gravitons, an initial energy for a massive graviton in space-time. The spatial values for the graviton production could be from the Planckian to Electro weak regime, with a nod to using a worm hole from a prior to a present universe as a delivery font for gravitational energy, as an information carrying bridge from prior universe 'information settings' to the present space-time. The number of Gravitons will be set as N, and the initial time, as a tie in with Barbour's ephemeris time, a constant times Planck time. In setting up the positions, as input into the positions and distributions of gravitons in our model, we will compare results as could be generated by Racetrack inflation, for presumed position of relic gravitons when just produced in the universe, as compared with results given by an adaptation of an argument presented by Crowell, in a modification of the Wheeler de Witt equation he gave germane to worm hole physics. In addition, with this presentation we will discuss entropy generation via graviton production. And compare that with semi classical arguments, as well as Brane – anti brane combinations. The idea will be to in all of this to re set the particulars of massive gravity in such a way as to revisit the outstanding problem of massive gravity: Its predictions do not match those of general relativity in the limit when a massive graviton mass approaches zero. In particular, while at small scales, Newton's gravitational law is recovered, the bending of light is only three quarters of the result Albert Einstein obtained in general relativity PACS 96.50.Ry, 98.80.-k, 98.80.Cq, 98.80.Bp

The Theory of Quantum Gravity Without Divergenies and Calculation of Cosmological Constant

Authors: T. Christolyubov, M. Christolyubova
Comments: 10 Pages.

To construct quantum gravity we introduce the quantum gravity state as function of particle coordinates and functional of fields, We add metric as the new argument of state: $$ \Psi=\Psi(t,x_{1},...x_{n},\lbrace A^{\gamma}(x)\rbrace, \lbrace g_{\mu\nu}(x) \rbrace) $$ we calculate the cosmological constant assuming that the quantum state is a function of time and radius of universe (mini-superspace) $$ \Psi=\Psi(t,a) $$ To avoid infinities in the solutions, we substitute the usual equation for propagotor with initial value Cauchy problem, which has finite and unique solution, for example we substitute the equation for Dirac electron propagator $$ (\gamma^\mu p_\mu - mc)K(t,x,t_0,x_0)= \delta(\vec{x} - \vec{x_0})\delta(t-t_0) $$ which already has infinity at the start $t = t_0 $, with the initial value Cauchy problem $$ \begin{cases} (H - i \hbar\partial / \partial t)K(t,x,t_0,x_0)=0,\\ K(t,x,t_0,x_0) = \delta(\vec{x} - \vec{x_0}),\quad t=t_0, \end{cases} $$ which has finite and unique solution.

Time-Resolved Measurement of Internal Conversion Dynamics in Strong-Field Molecular Ionization

Authors: Vincent Tagliamonti, Brian Kaufman, Arthur Zhao, Tamás Rozgonyi, Philipp Marquetand, Thomas Weinacht
Comments: 8 Pages.

We time-resolve coupled electronic and nuclear dynamics during strong-field molecular ionization by measuring the momentum-resolved photoelectron yield as a function of pump-probe delay for a pair of strong-field laser pulses. The sub-10-fs pulses are generated using a specially designed ultrafast optical pulse shaper and the electrons are measured using velocity map imaging. Our measurements, in conjunction with calculations that solve the time-dependent Schrödinger equation, allow us to time-resolve resonance-enhanced strong-field ionization and break it down into three basic steps: (1) Stark-shifted resonant excitation of a high-lying neutral state of the molecule, (2) nonadiabatic dynamics (internal conversion) in which multiple electronic states are coupled, and (3) coupling to the continuum (ionization) http://learnrnd.com/detail.php?id=Biowarfare_and_Germwarfare

Neutrino Mixing with Hopf Algebras

Authors: M. D. Sheppeard
Comments: 9 Pages.

Neutrino mixing in a spectral model for QFT employs the Bogoliubov transformation, which is a quantum Fourier transform. We look at the Hopf algebras in this setting, from a more motivic perspective. Experimental results for mixing are considered.

Was Polchinski Wrong? Colombeau Disributional Rindler Spacetime with Disributional Levi-Cività Connection Induced a Strong Vacuum Dominance. Unruh Effect Revisited

Authors: J. Foukzon, A. A. Potapov, E. R. Men’kova
Comments: 58 Pages.

The vacuum energy density of free scalar quantum field Φ in a Rindler distributional spacetime with distributional Levi-Cività connection is considered.It has been widely believed that, except in very extreme situations, the influence of acceleration on quantum fields should amount to just small, sub-dominant contributions. Here we argue that this belief is wrong by showing that in a Rindler distributional background spacetime with distributional Levi-Cività connection the vacuum energy of free quantum fields is forced, by the very same background distributional spacetime such a Rindler distributional background spacetime, to become dominant over any classical energy density component. This semiclassical gravity effect finds its roots in the singular behavior of quantum fields on a Rindler distributional spacetimes with distributional Levi-Cività connection. In particular we obtain that the vacuum fluctuations 〈2  has a singular behavior at a Rindler horizon   0 : 〈2~−4,  ≈ c2/a,a → . Therefore sufficiently strongly accelerated observer burns up near the Rindler horizon. Thus Polchinski’s account doesn’t violation of the Einstein equivalence principle.

The Generation Mechanism of the Distortion of Space by Mass is Described in Figure.

Authors: Terubumi Honjou
Comments: 5 Pages.

In modern physics, understanding of gravity is perfectly understood by the general theory of relativity. By the general relativity and its gravitational equations, gravity is understood to be a distortion of the space around mass forming. The state of distortion in the space is perfectly explained by solving the gravitational equation. However, neither Newton nor Einstein's general relativity explains the cause that the space around the mass distorts, and the space is distorted by what kind of mechanism. The model of my hypothesis "particle pulsation principle" can explain the mechanism of the generation of gravity (distortion of space) in the figure.

Showing Fjortof’s Theorem Does not Apply for Defining Instability for Early Universe Thermodynamic Potentials. Asking if Nucleated Particles Result At/before Electro-Weak Era Due to Injection of Matter-Energy at the Big Bang?

Authors: Andrew Beckwith
Comments: 16 Pages. Identical to last version. Changed my name, to Andrew Beckwith, so it is easier to find

This paper uses the “Fjortoft theorem” for defining necessary conditions for instability. The point is that it does not apply in the vicinity of the big bang. We apply this theorem to what is called by T. Padmanabhan a thermodynamic potential which becomes would be unstable if conditions for the applications of “Fjortoft’s theorem” hold. In our case, there is no instability, so a different mechanism has to be appealed to. In the case of vacuum nucleation, we argue that conditions exist for the nucleation of particles as of the electroweak regime. Due to injecting material from a node point, in spacetime. This regime of early universe creation, coexits with the failure of applications of “Fjortoft” theorem in such a way as to give necessary and sufficient conditons for matter creation, in a way similar to the Higgs Boson. Key words: Fjortoft theorem, thermodynamic potential, matter creation, Higgs Boson.

Quantum Gravity and the Titius-Bode Rule

Authors: Dezso Sarkadi
Comments: 6 Pages.

Today, in the areas of theoretical foundation and experimental verification, there is great interest in the properties of a future Quantum Gravity. The ultimate goal of the present research is to contribute to the creation of a definitive, universally acceptable, theory of Quantum Gravity. In the present paper, the two hundred and fifty years of history of the empirical Titius-Bode rule is investigated, under the assumption that this rule is key evidence for a quantum feature in the already long-known classical gravity. Keywords: Titius-Bode rule, Bohr-Sommerfeld quantization, de Broglie matter wave, Quantum Gravity.
