Alter Coherence of Light

Authors: George Rajna
Comments: 17 Pages.

Brown University researchers have demonstrated for the first time a method of substantially changing the spatial coherence of light. [12] Researchers at the University of Central Florida have generated what is being deemed the fastest light pulse ever developed. [11] Physicists at Chalmers University of Technology and Free University of Brussels have now found a method to significantly enhance optical force. [10] Nature Communications today published research by a team comprising Scottish and South African researchers, demonstrating entanglement swapping and teleportation of orbital angular momentum 'patterns' of light. [9] While physicists are continually looking for ways to unify the theory of relativity, which describes large-scale phenomena, with quantum theory, which describes small-scale phenomena, computer scientists are searching for technologies to build the quantum computer using Quantum Information. In August 2013, the achievement of "fully deterministic" quantum teleportation, using a hybrid technique, was reported. On 29 May 2014, scientists announced a reliable way of transferring data by quantum teleportation. Quantum teleportation of data had been done before but with highly unreliable methods. The accelerating electrons explain not only the Maxwell Equations and the Special Relativity, but the Heisenberg Uncertainty Relation, the Wave-Particle Duality and the electron's spin also, building the Bridge between the Classical and Quantum Theories. The Planck Distribution Law of the electromagnetic oscillators explains the electron/proton mass rate and the Weak and Strong Interactions by the diffraction patterns. The Weak Interaction changes the diffraction patterns by moving the electric charge from one side to the other side of the diffraction pattern, which violates the CP and Time reversal symmetry. The diffraction patterns and the locality of the self-maintaining electromagnetic potential explains also the Quantum Entanglement, giving it as a natural part of the Relativistic Quantum Theory and making possible to build the Quantum Computer with the help of Quantum Information.

The Connection Between Collective Diffusion in Classic Liquids and the Superfluidity Phenomenon in Quantum Liquids

Authors: Alekseenko Victor Victorovich
Comments: 12 Pages.

This study suggests the mechanism for atomic motion in quantum liquids at low temperatures where the lifetime of the states that are responsible for atomic motion becomes macroscopically long. This mechanism is an analog to the motion of crowdions in the one-dimensional Frenkel-Kontorova model. Soliton-like atomic motion along linear directions, and the circular motions provide a means of explaining many macroscopic phenomena occurring at the transition of 4He to a superfluid state, such as the behavior of rotating superfluid helium and the flow potentiality of the superfluid phase. The thermodynamics of rotating 4He is considered under the assumption that Bose-Einstein condensate is not the ground state of Bose-Einstein liquid. An experiment is suggested in order to validate our approach.

A Monte Carlo Implementation of the Ising Model in Python

Authors: Alexey Khorev
Comments: 7 Pages.

This article explores an implementation of the 2D Ising model using the Metropolis algorithm in the Python programming language. The goal of this work was to explore the scope of behaviours this model can demonstrate through a simplistic implementation on a relatively low-end machine. The Ising model itself is particularly interesting as it demonstrates relatively complex behaviours of ferromagnetics e.g. the second-order phase transition in spite of its simplicity. To study the specifics of this model several parameters were measured (namely the net magnetization and energy, the specific heat and correlation function) and a visualization of the grid was implemented. The simulations demonstrated an easily observable phase transition near critical temperature on a 100 × 100 Ising grid with the measured parameters behaving nearly as predicted by the exact solution developed for this model.
