 de in the study of many-body systems out of equilibrium\, where certain in
 tegrable models have played a significant role in our understanding of spe
 cific but prototypical problems. Even in these cases\, however\, the full 
 relaxation dynamics has proven to be hard to tackle in the presence of int
 eractions\, both analytically and numerically. In this talk\, I will discu
 ss how analytically tractable systems may be obtained by considering 1D 
 “quantum circuit’’ toy models for the many-body dynamics\, allowing 
 for analytic solutions even in the absence of conservation laws (i.e. inte
 grability). I will focus on a class of chaotic “dual-unitary” quantum 
 circuits\, and certain integrable quantum cellular automata\, showing that
  in both cases the dynamics of correlation functions and entanglement can 
 be described exactly. Our approach is based on a representation of the eff
 ect of the global evolution on finite subsystems in terms of tensor networ
 ks\, which is applicable even beyond the exactly solvable cases presented.
  I will conclude by discussing how related ideas may lead to the construct
 ion of more general solvable dynamics beyond integrability.
