Contradiction of the DENSITY MATRIX notion in quantum mechanics
Contradiction of the DENSITY MATRIX notion quantum mechanics General Physics
2012/4/19
It is shown that description of a nonpolarized neutron beam by density matrix is contradictory. Density matrix is invariant with respect to choice of quantization axis, while experimental devices can ...
Derivation of the Schrodinger equation from the Hamilton-Jacobi equation in Feynman's path integral formulation of quantum mechanics
Derivation of the Schrodinger equation Hamilton-Jacobi equation Feynman's path integral formulation of quantum mechanics
2012/4/19
It is shown how the time-dependent Schr\"{o}dinger equation may be simply derived from the dynamical postulate of Feynman's path integral formulation of quantum mechanics and the Hamilton-Jacobi equat...
Quantum Mechanics versus Special Relativity: A forgotten conflict
quantum mechanics special relativity quantum collapse quantum entanglement space-time causation separability locality non-locality asymptotic independence
2011/9/6
Despite the widespread assumptions on the compatibility between non-relativistic quantum mechanics and special relativity, there still remains a considerable amount of unresolved problems to which few...
Supersymmetric Quantum Mechanics with Reflections

2011/9/22
Abstract: We consider a realization of supersymmetric quantum mechanics where supercharges are differential-difference operators with reflections. A supersymmetric system with an extended Scarf I pote...
A Euclidean formulation of relativistic quantum mechanics
relativistic quantum mechanics Euclidean formulation
2011/7/20
In this paper we discuss a formulation of relativistic quantum mechanics that uses Euclidean Green functions or generating functionals as input.
Elementary Considerations on the Interpretation of the Foundations of Quantum Mechanics
Elementary Considerations Interpretation the Foundations Quantum Mechanics
2011/8/5
Abstract: This paper appeared in a collection of papers titled "Scientific Papers Presented to Max Born on his retirement from the Tait Chair of Natural Philosophy in the University of Edinburgh", pub...
PT symmetry in relativistic quantum mechanics
PT symmetry relativistic quantum mechanics High Energy Physics - Theory
2011/9/29
Abstract: In nonrelativistic quantum mechanics and in relativistic quantum field theory, time t is a parameter and thus the time-reversal operator T does not actually reverse the sign of t. However, i...
Nonlinear Boundaries in Quantum Mechanics
Nonlinear Boundaries Quantum Mechanics Quantum Physics
2011/7/28
Abstract: Based on empirical evidence, quantum eigenvalue equations appear to be strictly linear and gauge invariant. This work uses concise mathematics to show that quantum eigenvalue equations on a ...
Unstable particles in non-relativistic quantum mechanics?
non-relativistic quantum mechanics Unstable particles Quantum Physics
2011/7/26
Abstract: The Schroedinger equation is up-to-a-phase invariant under the Galilei group. This phase leads to the Bargmann's superselection rule, which forbids the existence of the superposition of stat...
The interpretation of quantum mechanics and of probability: Identical role of the 'observer'
quantum mechanics probability
2011/9/14
The aim of the article is to argue that the interpretations of quantum mechanics and of probability are much closer than usually thought. Indeed, a detailed analysis of the concept of probability (wit...
An Investigation on the Basic Conceptual Foundations of Quantum Mechanics by Using the Clifford Algebra
Clifford algebra, foundations of quantum mechanics, wave function collapse,quantum mechanics and conceptual entities, von Neumann postulates on quantum measurement
2011/9/2
We review our approach to quantum mechanics adding also some new interesting results. We start by giving proof of two important theorems ms on the existence of the A(Si) and i,±1 N Clifford algebras. ...
Time separation as a hidden variable to the Copenhagen school of quantum mechanics

2010/12/27
The Bohr radius is a space-like separation between the proton and electron in the hydrogen atom. According to the Copenhagen school of quantum mechanics, the proton is sitting in the absolute Lorentz ...
We study the tunneling through delta and double delta potentials in fractional quantum mechanics. After solving the fractional Schr\"odinger equation for these potentials, we calculate the correspond...
We consider the canonical quantization of an ordinary fluid. The resulting long-distance effective field theory is derivatively coupled, and therefore strongly coupled in the UV. The system however ex...
Numerical approach to SUSY quantum mechanics and the gauge/gravity duality
SUSY quantum mechanics the gauge/gravity duality
2011/1/7
We demonstrate that Monte-Carlo simulation is a practical tool to study nonperturbative aspects of supersymmetric quantum mechanics. As an example we study D0-brane quantum mechanics in the context of...
