Causality and Chance in Relativistic Quantum Field Theories
Local causality Microcausality Bell correlations Relativistic quantum field theories Pragmatist interpretation Causal intervention
2016/6/13
Bell appealed to the theory of relativity in formulating his principle of local causality. But he maintained that quantum field theories do not conform to that principle, even when their field equatio...
The GRW flash theory:a relativistic quantum ontology of matter in space-time?
Bell’s theorem Bohmian mechanics collapse of the wave-function dispositionalism GRW flash GRW mass density Humeanism Lorentz-invariance primitive ontology propensities relativistic collapse theory
2016/6/13
John Bell proposed an ontology for the GRW modification of quantum mechanics in terms of flashes occurring at space-time points. The paper spells out the motivation for this ontology, enquires into th...
Pragmatists and Purists on CPT Invariance in Relativistic Quantum Field Theories
quantum field theory CPT theorem causal perturbation theory
2016/6/12
Philosophers of physics are split on whether foundational issues in relativistic quantum field theory (RQFT) should be framed within pragmatist approaches, which trade mathematical rigor for the abili...
Relativistic Quantum and Classical Mechanics in the Hilbert Space
Relativistic Quantum Classical Mechanics the Hilbert Space
2011/8/18
Abstract: We present a formulation of relativistic classical and quantum mechanics in the Hilbert space with a linkage through the Ehrenfest quantization. We start with the covariant form of the Loren...
A Euclidean formulation of relativistic quantum mechanics

2011/7/20
In this paper we discuss a formulation of relativistic quantum mechanics that uses Euclidean Green functions or generating functionals as input.
Relativistic Quantum State, Geometric Phase and Dissipationless Spin current
Relativistic Quantum State Geometric Phase Dissipationless Spin current
2011/8/11
Abstract: Spin current of a Dirac particle is shown to be given by the geometric phase and in terms of the later, a closed form expression is obtained for the dissipationlessness of the spin current.
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...
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...
Relativistic quantum theory of high harmonic generation on atoms/ions by strong laser fields

2011/9/1
High-order harmonic generation (HHG) by hydrogenlike atoms/ions in the uniform periodic electric field, formed by the two linearly polarized counterpropagating laser beams of relativistic intensities,...
Quadratic Algebra Approach to Relativistic Quantum Smorodinsky-Winternitz Systems
Quadratic Algebra Relativistic Quantum Smorodinsky-Winternitz Systems
2011/1/19
There exist a relation between the Klein-Gordon and the Dirac equations with scalar and vector potentials of equal magnitude (SVPEM) and the Schrödinger equation.
On a nonlinear problem intervening in relativistic quantum mechanics perturbed by a factor of amortizement
nonlinear hyperbolic problem perturbed amortizement
2010/9/25
In this work, we study the existence and the uniqueness and the regularity of the solution of a problem governed by a nonlinear equation intervening in relativistic quantum mechanics perturbed by an a...

Timeless path integral for relativistic quantum mechanics
Timeless path relativistic quantum mechanics
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...
