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
2010/11/11
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...
Explaining the Unobserved: Why Quantum Mechanics Is Not only About Information
Quantum information Collapse theories Crucial experiments Constructive theories
2011/9/8
A remarkable theorem by Clifton, Bub and Halverson (2003) (CBH) characterizes quantum theory in terms of information--theoretic principles. According to Bub (2004, 2005) the philosophical significance...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
modal interpretation relational properties, measurement realism
2011/9/7
We study the process of observation (measurement), within the framework of a `perspectival' (`relational', `relative state')version of the modal interpretation of quantum mechanics. We show that if we...

Quantum mechanics modal interpretations relational properties relativity Lorentz invariance
2011/9/7
Recent no go theorems by Dickson and Clifton (1998), Arntzenius (1998) and Myrvold (2002) demonstrate that current modal interpretations are incompatible with relativity. In this paper we propose stra...
Dieks' Realistic Interpretation of Quantum Mechanics: A Comment
quantum mechanics interpretation probabilities psychophysical parallelism
2011/9/7
D. Dieks has proposed a semantical rule which he claims yields a realistic interpretation of the formalism of quantum mechanics without the projection postulate. I argue that his proposal is unaccepta...
Measurement and Classical Regime in Quantum Mechanics
quantum mechanics measurement problem classica regime decoherence
2011/9/7
This article (for the Oxford Handbook of Philosophy of Physics) focuses on two of the main problems raising interpretational issues in quantum mechanics, namely the notorious measurement problem and t...
A Philosopher's View of the Epistemic Interpretation of Quantum Mechanics
epistemic interpretation toy model chocolate quiz show
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...
Quantum Mechanics versus Special Relativity: A forgotten conflict
quantum mechanics quantum entanglement causation separability locality
2011/9/7
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...
Is Quantum Mechanics An Island in Theoryspace?
quantum computing nonlinear quantum mechanics origins quantum measurement rule
2011/9/7
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...
On the classical limit of quantum mechanics and the threat of fundamental graininess and chaos to the correspondence principle
classical limit of quantum mechanics fundamental graininess and chaos correspondence principle
2010/10/21
The aim of this paper is to review the classical limit of Quantum Mechanics and to precise the well known threat of chaos (and fundamental graininess) to the correspondence principle. We will introduc...
Classical and Quantum Fisher Information in the Geometrical Formulation of Quantum Mechanics
Classical Quantum Fisher Information Geometrical Formulation Quantum Mechanics
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
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 ...
Phase Space Quantum Mechanics

2010/10/21
The paper review and develop the alternative formulation of quantum mechanics known as the phase space quantum mechanics or deformation quantization. It is shown that the quantization naturally arises...
