Supersymmetrical Separation of Variables in Two-Dimensional Quantum Mechanics
supersymmetry separation of variables integrability solvability
font style='font-size:12px;'>
2010/12/13
Two different approaches are formulated to analyze two-dimensional quantum models which are not amenable to standard separation of variables. Both methods are essentially based on supersymmetrical sec...
Quantum mechanics, by itself, implies perception of a classical world
Quantum mechanics implies perception classical world

Quantum mechanics, although highly successful, has two peculiarities. First, in many situations it gives more than one potential version of reality. And second, the wave function for a macroscopic obj...
Basic quantum mechanics for three Dirac equations in a curved spacetime
Dirac equation gravitation current conservation Hermitian Hamiltonian tensor representation
font style='font-size:12px;'>
2010/6/30
We study the basic quantum mechanics for a fully general set of Dirac matrices in a curved spacetime by extending Pauli’s method. We further extend this study to three versions of the Dirac equation: ...

2010/3/10
The effect of nonlinear friction forces in quantum mechanics is studied via dissipative Madelung hydrodynamics. A new thermo-quantum diffusion equation is derived, which is solved for the particular c...

2010/2/23
Physicists in Canada and Australia have shown that nature exploits quantum mechanics to make photosynthesis more efficient. By probing light-harvesting proteins within algae using laser beams, the res...
Neutrino oscillations: Quantum mechanics vs. quantum field theory
Neutrino oscillations Quantum mechanics
font style='font-size:12px;'>
2010/3/15
A consistent description of neutrino oscillations requires either the quantum-mechanical (QM) wave packet approach or a quantum field theoretic (QFT) treatment. We compare these two approaches to neut...
Morlet wavelets in quantum mechanics
Morlet wavelets quantum mechanics
font style='font-size:12px;'>
2010/3/10
Wavelets offer significant advantages for the analysis of problems in quantum mechanics. Because wavelets are localized in both time and frequency they avoid certain subtle but potentially fatal conce...
The basic paradoxes of statistical classical physics and the quantum mechanics
Observable Dynamics Idel Dynamics Unpredictable Dynamics self-knowledge correlations
font style='font-size:12px;'>
2010/4/7
The statistical classical mechanics and the quantum mechanics are two developed and well-known theories. The described two theories are known and well studied for a long time. Nevertheless, they conta...
Deformed Clifford algebra and supersymmetric quantum mechanics on a phase space with applications in quantum optics
Cliff ord algebra supersymmetric quantum mechanics deformation quantization Wigner functions Jaynes-Cummings models
font style='font-size:12px;'>
2010/4/13
In order to realize supersymmetric quantum mechanics methods on a four dimensional classical phase-space, the complexified Clifford algebra of this space is extended by deforming it with the Moyal sta...
Landau problem in noncommutative quantum mechanics

font style='font-size:12px;'>
2009/7/31
The Landau problem in non-commutative quantum mechanics (NCQM) is studied. First by solving the Schrodinger equations on noncommutative (NC) space we obtain the Landau energy levels and the energy cor...

One World, One Reality, and the Everett Relaltive State Interpretation of Quantum Mechanics
Foundations of Quantum Mechanics Many worlds Measurement theory Interpretation of Quantum Mechanics
font style='font-size:12px;'>
2010/4/12
We modify the Relative State Interpretation (RSI) of Quantum Mechanics so that it does not imply many worlds and parallel realities. We drop the assumption that probability amplitudes correspond one-t...

2010/4/8
In the many-worlds interpretations (MWIs) of Everett and others, if I am the observer, there are several versions of me but no version is singled out as the one corresponding to my perceptions. Howeve...
Can quantum mechanics be an emergent phenomenon?
quantum mechanics emergent phenomenon
font style='font-size:12px;'>
2010/4/9
We raise the issue whether conventional quantum mechanics, which is not a hidden variable theory in the usual Jauch-Piron's sense, might nevertheless be a hidden variable theory in the sense recently ...
