Title: Floquet Systems-Ensembles and Order Under Periodic Driving

Abstract:

We study the long-time behaviour of many-body Floquet systems--many-body
quantum systems under temporally periodic driving, arguably the simplest 
deviation
from equilibrium.


We begin by showing that generically such interacting systems heat up, 
then focus
on two ways to prevent this: integrability and disorder. We show that 
the nontrivial
steady states thus achieved may host nontrivial phases and focus on the 
recently
observed example of "time crystals". Finally we close with some remarks 
on open
floquet systems.
