Incompatibility of the de Broglie-Bohm Theory with Quantum Mechanics
Incompatibility Theory with Quantum Mechanics
font style='font-size:12px;'>
2010/10/13
It is shown that although the de Broglie-Bohm quantum theory of motion is equivalent to standard quantum mechanics when averages of dynamical variables are taken over a Gibbs ensemble of Bohmian traje...

Quantum Mechanics Curved Hypersurfaces
font style='font-size:12px;'>
2010/11/11
In this work, Schr\"odinger and Dirac equations will be examined in geometries that confine the particles to hypersurfaces. For this purpose, two methods will be considered. The first method is the th...
Generalized Spin and Pseudo-Spin Symmetry: Relativistic Extension of Supersymmetric Quantum Mechanics
Generalized Spin Pseudo-Spin Symmetry Relativistic Extension Supersymmetric Quantum Mechanics

We consider the Dirac equation in 1+1 space-time dimension with vector, scalar and pseudo-scalar coupling. In the traditional spin (or pseudo-spin) symmetry, the difference between (or sum of) the sca...

2011/9/7
There are various reasons for favouring Ψ-epistemic interpretations of quantum mechanics over Ψ-ontic interpretations. One such reason is the correlation between quantum mechanics and Liouville dynami...

This paper investigates what happens if we change quantum mechanics in several ways. The main results are as follows. First, if we replace the 2-norm by some other p-norm, then there are no nontrivial...
Classical and Quantum Fisher Information in the Geometrical Formulation of Quantum Mechanics
Classical Quantum Fisher Information Geometrical Formulation Quantum Mechanics
font style='font-size:12px;'>
2010/10/21
The tomographic picture of quantum mechanics has brought the description of quantum states closer to that of classical probability and statistics. On the other hand, the geometrical
formulation of qu...
Supersymmetrical Separation of Variables in Two-Dimensional Quantum Mechanics
supersymmetry separation of variables integrability solvability
font style='font-size:12px;'>
2010/10/27
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 s...
Complementarity in categorical quantum mechanics
Complementarity categorical quantum mechanics

2010/10/19
We relate notions of complementarity in three layers of quantum mechanics:(i) von Neumann algebras, (ii) Hilbert spaces, and (iii) orthomodular lattices. Taking a more general categorical perspective ...

2010/10/27
Starting from the canonical formalism of relativistic (timeless) quantum mechanics, the formulation of timeless path integral is rigorously derived. The transition amplitude is reformulated as the sum...
Foundations of quantum mechanics: decoherence and interpretation
font style='font-size:12px;'>
2010/10/18
In this paper we review Castagnino’s contributions to the foundations of quantum mechanics. First, we recall his work on quantum decoherence in closed systems, and the proposal of a general framework ...

2010/10/21
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...
