Condensation time scale of a stochastic transport process with pair factorized steady states — •Hannes Nagel1, Bartlomiej Waclaw2, and Wolfhard Janke1 — 1Institut für Theoretische Physik, Universität Leipzig, Germany — 2School of Physics & Astronomy, The University of Edinburgh, UK
Stochastic transport processes (such as [1]) can be tuned by their generating weight functions to exhibit a steady state with a condensate of particles that is separate from a fluid background phase. We study the dynamics of the relaxation into the steady state of such driven transport systems using numerical simulations to determine the condensation time scale and discuss the corresponding phenomenologic mechanisms. Despite the existence of short-range interactions in the studied system, the condensation behavior is found to be quite similar to that of the zero-range process on one- and two-dimensional lattices.
