Spreading of correlations in Markovian open quantum systems
Vincenzo Alba, Federico Carollo
Abstract
The spreading of information forms the basis of several quantum nonequilibrium phenomena, such as seen in the emergence of thermodynamics and statistical physics. Recently, much progress has been made in understanding the dynamics of information in isolated integrable systems after a quantum quench, by using a quasiparticle picture predicting ballistic spreading of quantum correlations. This paper shows how to apply these ideas to describe the dissipative dynamics of correlations and of entanglement in open quantum many-body systems.
