Canonical Typicality
Sheldon Goldstein, Joel L. Lebowitz, Roderich Tumulka +1
It is well known that a system, S, weakly coupled to a heat bath, B, is described by the canonical ensemble when the composite, S+B, is described by the microcanonical ensemble cor…
Smoothness of Wave Functions in Thermal Equilibrium
Roderich Tumulka, Nino Zanghi
We consider the thermal equilibrium distribution at inverse temperature , or canonical ensemble, of the wave function of a quantum system. Since spaces contain more no…
On Superselection Rules in Bohm-Bell Theories
Samuel Colin, Thomas Durt, Roderich Tumulka
The meaning of superselection rules in Bohm-Bell theories (i.e., quantum theories with particle trajectories) is different from that in orthodox quantum theory. More precisely, the…
The Analogue of Bohm-Bell Processes on a Graph
Roderich Tumulka
Bohm-Bell processes, of interest in the foundations of quantum field theory, form a class of Markov processes generalizing in a natural way both Bohm's dynamical system in co…
On Spontaneous Wave Function Collapse and Quantum Field Theory
Roderich Tumulka
One way of obtaining a version of quantum mechanics without observers, and thus of solving the paradoxes of quantum mechanics, is to modify the Schroedinger evolution by implementi…
Quantum Mechanics in Multiply-Connected Spaces
Detlef Duerr, Sheldon Goldstein, James Taylor +2
We explain why, in a configuration space that is multiply connected, i.e., whose fundamental group is nontrivial, there are several quantum theories, corresponding to different cho…
Bell's Jump Process in Discrete Time
Jonathan Barrett, Matthew Leifer, Roderich Tumulka
The jump process introduced by J. S. Bell in 1986, for defining a quantum field theory without observers, presupposes that space is discrete whereas time is continuous. In this let…
Feynman's Path Integrals and Bohm's Particle Paths
Roderich Tumulka
Both Bohmian mechanics, a version of quantum mechanics with trajectories, and Feynman's path integral formalism have something to do with particle paths in space and time. The ques…
