Some Jump Processes in Quantum Field Theory
Roderich Tumulka, Hans-Otto Georgii
A jump process for the positions of interacting quantum particles on a lattice, with time-dependent transition rates governed by the state vector, was first considered by J.S. Bell…

Global Existence of Bell's Time-Inhomogeneous Jump Process for Lattice Quantum Field Theory
Hans-Otto Georgii, Roderich Tumulka
We consider the time-inhomogeneous Markovian jump process introduced by John S. Bell [Phys.Rep. 137, 49] for a lattice quantum field theory, which runs on the associated configurat…

Phase transition and percolation in Gibbsian particle models
H. -O. Georgii
We discuss the interrelation between phase transitions in interacting lattice or continuum models, and the existence of infinite clusters in suitable random-graph models. In partic…
