The Many-Worlds Interpretation of Quantum Mechanics is Fatally Flawed
The Many-Worlds Interpretation Quantum Mechanics Fatally Flawed

The linear mathematics of quantum mechanics gives many versions of reality instead of the single version we perceive, with the perceived version chosen at random according to a probability law. Becau...
A realist interpretation of quantum mechanics based on undecidability due to gravity

We summarize several recent developments suggesting that solving the problem of time in quantum gravity leads to a solution of the measurement problem in quantum mechanics. This approach has been info...
Classical and Quantum Mechanics with Poincare-Snyder Relativity
Classical Quantum Mechanics Poincare-Snyder Relativity
font style='font-size:12px;'>
2010/11/11
The Poincar\'e-Snyder relativity was introduced in an earlier paper of ours as an extended form of Einstein relativity obtained by appropriate limiting setting of the full Quantum Relativity. The latt...
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...

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
font style='font-size:12px;'>
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
font style='font-size:12px;'>
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...
A perspectival version of the modal interpretation of quantum mechanics and the origin of macroscopic behavior
Quantum mechanics modal interpretations relational properties relativity Lorentz invariance
font style='font-size:12px;'>
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

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...

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

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...

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
font style='font-size:12px;'>
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...
