DESCRIPTION:The out-of-equilibrium dynamics of interacting many-body syste
 ms presents one of the most challenging problems in modern physics with im
 plications ranging from thermalization dynamics over the formation of orde
 r to questions at the heart of quantum complexity and quantum information 
 processing. \nTraditionally\, however\, out-of-equilibrium dynamics was mo
 stly confined to short transients\, since typical systems would ultimately
  relax back into well-understood—and rather boring—thermal states. Dur
 ing this thermalization\, all quantum information present in the initial s
 tate is spread over the whole system and thereby becomes inaccessible. \nI
 n this talk\, I will demonstrate that synthetic many-body systems offer ac
 cess to intrinsically non-ergodic dynamics\, where a quantum non-equilibri
 um system can beat thermodynamics and never relax to a thermal state. \nWe
  use ultracold atoms in optical lattices as a very versatile platform to s
 tudy quantum many-body physics in a clean and well-controlled environment.
  One example\, connected to ‘classical’ integrability\, is the sudden 
 expansion of hard-core lattice bosons. The second\, more generic example i
 s the experimental realization of Many-Body Localization of interacting fe
 rmions\, where the presence of disorder creates a non-ergodic state that w
 ill\, in a closed system\, never thermalize\, and preserve some local memo
 ry of the initial conditions for all times.
