• Abstract: We give a pedagogical introduction to the Generalized Hydrodynamic approach to inhomogeneous quenches in integrable many-body quantum systems. We review recent applications of the theory, focusing in particular on two classes of problems: bipartitioning protocols and trap quenches, which represent two prototypical examples of broken translational symmetry in either the system initial state or post-quench Hamiltonian. We report on exact results that have been obtained for generic time-dependent correlation functions and entanglement evolution, and discuss in detail the range of applicability of the theory. Finally, we present some open questions and suggest perspectives on possible future directions.

• Ergodic repeated interaction quantum systems: Steady states and reducibility theory [0.0]
  We consider the time evolution of an open quantum system subject to a sequence of random quantum channels with a stationary distribution. Various specific models of disorder in repeated interaction models have been considered. We develop a reducarity theory for general stationary random repeated interaction models without this condition.

  Recent years have seen tremendous progress in the theoretical understanding of quantum systems driven dissipatively. We first provide an overarching view of the models of boundary-driven open quantum systems, both in the weak and strong coupling regimes. This is followed by a review of state-of-the-art analytical and numerical methods, both exact, perturbative and approximate.

We conclude that such an approximation always leads to a Markovian evolution for the considered class of dynamics.
