Description
Abstract: Complex quantum systems out of equilibrium are
at the basis of a number of long-standing questions in
physics. This talk will be concerned on the one hand with
recent progress on understanding how quantum many-body
systems out of equilibrium eventually come to rest,
thermalise and cross phase transitions, on the other hand
with dynamical analogue quantum simulations using cold
atoms [1-4]. In an outlook, we will discuss the question of
certification of quantum simulators, and will how this
problem also arises in other related settings, such as in
Boson samplers [5,6].
