Dynamic Kibble-Zurek scaling framework for open dissipative many-body systems crossing quantum transitions

Abstract

This paper shows how open quantum systems subject to a slow passage across a Kibble-Zurek protocol can develop a universal dynamic scaling regime similar to that emerging in closed systems. The authors show that a fine tuning of the system-bath coupling is required and its decay rate should scale as a specific power of the time scale of the protocol, with the exponent being controlled by the universality class of the quantum transition.
