SUMMARY:Universal dynamics of entanglement and quantum operators from rand
 om unitary circuits - Adam Nahum (Oxford)

DESCRIPTION:Isolated quantum many-body systems\, if initialised in states 
 of low entanglement\, typically evolve towards states of high (volume law)
  entanglement. I will describe how simple minimal models for many-body dyn
 amics — quantum circuits made up of randomly chosen gates — yield a co
 arse-grained description for this process of entanglement production. This
  description involves a minimal ‘membrane’ in spacetime. I will also d
 escribe universal results for the spreading of local perturbations (the 
 ‘out-of-time-order correlator’) obtained from random unitary circuits.
