Axiomatizing Relativistic Dynamics using Formal Thought Experiments
First-order Modal Logic Relativistic Dynamics Thought Experiments Definition of Mass
2016/6/14
Thought experiments are widely used in the informal explanation of Relativity Theories; however, they are not present explicitly in formalized versions of Relativity Theory. In this paper, we present ...
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...
On the Composition of Two-Prover Commitments, and Applications to Multi-Round Relativistic Commitments
bit commitment two provers
2016/2/23
We consider the related notions of two-prover and of relativistic
commitment schemes. In recent work, Lunghi et al. proposed a
new relativistic commitment scheme with a multi-round sustain phase

Finite Volume Local Evolution Galerkin Method for Two-dimensional Relativistic Hydrodynamics
Finite volume local evolution Galerkin method evolution operator genuinely multi-dimensional method relativistic hydrodynamics
2014/9/26
The paper proposes a second-order accurate nite volume local evolution Galerkin
(FVLEG) method for two-dimensional special relativistic hydrodynamical (RHD) e-quations. Instead of using the dimensio...
A third-order accurate direct Eulerian GRP scheme for one-dimensional relativistic hydrodynamics
Godunov-type scheme WENO Generalized Riemann problem Riemann problem
2014/9/26
The paper analytically derives a third-order accurate direct Eulerian general-ized Riemann problem (GRP) scheme for one-dimensional special relativistic hydrody-namical equations. In our GRP scheme, t...
Perturbing E®ects of a Close Star on Relativistic Precessions of a Star in Galactic Center
black hole physics Galaxy:center relativity
2013/4/9
As proposed by Cli®ord M.Will, observations of the precessing orbits of a class of stars around the supermassive black hole in the galactic center with very short period(O(0:1) yr) could provide ...
Relativistic forces in Lagangian mechanics
Relativistic forces Lagangian mechanics Mathematical Physics
2012/6/27
We give a general definition of \emph{relativistic force} in the context of Lagrangian mechanics. Once this is done we prove that the only relativistic forces which are linear on the velocities are th...
Relativistic point dynamics and Einstein formula as a property of localized solutions of a nonlinear Klein-Gordon equation
Relativistic point dynamics Einstein formula nonlinear Klein-Gordon equation Mathematical Physics
2012/6/15
Einstein's relation E=Mc^2 between the energy E and the mass M is the cornerstone of the relativity theory. This relation is often derived in a context of the relativistic theory for closed systems wh...
Under-the-barrier dynamics in laser-induced relativistic tunneling
Under-the-barrier dynamics laser-induced relativistic tunneling Atomic Physics
2012/5/29
The tunneling dynamics in relativistic strong-field ionization is investigated with the aim to develop an intuitive picture for the relativistic tunneling regime. We demonstrate that the tunneling pic...
We present a systematic hierarchy of approximations for {\it local} exact-decoupling of four-component quantum chemical Hamiltonians based on the Dirac equation. Our ansatz reaches beyond the trivial ...
On the Relativistic Formulation of Matter
General Relativity and Gravitation - theory fundamental problems and general formalism
2012/4/20
A critical analysis of the relativistic formulation of matter reveals some surprising inconsistencies and paradoxes. Corrections are discovered which lead to the long-sought-after equality of the grav...
