Stefan Florchinger, "A quantum information perspective on relativistic fluid dynamics and quantum fields out-of-equilibrium"

There is a fascinating relation between the dynamics of quantum fields and information theory formulated in terms of entropy. While this is well known and understood in thermal equilibrium, the extension to non-equilibrium dynamics is a topic of current research. I will discuss how in quantum field theory entropy results from entanglement between different regions and how local dissipation can be understood as entanglement generation. This provides a new view on relativistic fluid dynamics. I will also discuss that apparent local thermalization can result from the space-time dynamics of entanglement, specifically for an expanding QCD string.
