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… 
Entanglement dynamics in Rule 54: Exact results and quasiparticle picture
We study the entanglement dynamics generated by quantum quenches in the quantum cellular automaton Rule 54. We consider the evolution from a recently introduced class of solvable initial states.
Hydrodynamics of quantum entropies in Ising chains with linear dissipation
We study the dynamics of quantum information and of quantum correlations after a quantum quench, in transverse field Ising chains subject to generic linear dissipation. As we show, in the
Hydrodynamics of weak integrability breaking
We review recent progress in understanding nearly integrable models within the framework of generalized hydrodynamics (GHD). Integrable systems have infinitely many conserved quantities and stable
Exact entanglement growth of a one-dimensional hard-core quantum gas during a free expansion
We consider the non-equilibrium dynamics of the entanglement entropy of a one-dimensional quantum gas of hard-core particles, initially confined in a box potential at zero temperature. At t = 0 the
Unbounded entanglement production via a dissipative impurity
We investigate the entanglement dynamics in a free-fermion chain initially prepared in a Fermi sea and subjected to localized losses (dissipative impurity). We derive a formula describing the
Macroscopic Effects of Localized Measurements in Jammed States of Quantum Spin Chains.
A quantum jammed state can be seen as a state where the phase space available to particles shrinks to zero, an interpretation quite accurate in integrable systems, where stable quasiparticles scatter
Correlation functions and transport coefficients in generalised hydrodynamics
We review the recent advances on exact results for dynamical correlation functions at large scales and related transport coefficients in interacting integrable models. We discuss Drude weights,
Fragmentation and Emergent Integrable Transport in the Weakly Tilted Ising Chain
We investigate emergent quantum dynamics of the tilted Ising chain in the regime of a weak transverse field. Within the leading order perturbation theory, the Hilbert space is fragmented into
Dynamics of Fluctuations in the Open Quantum SSEP and Free Probability
The quantum symmetric simple exclusion process (Q-SSEP) is a simple model of spinless fermions hopping on a one-dimensional chain to neighboring sites with random amplitudes. It was proposed as a toy
Growth of entanglement entropy under local projective measurements
Non-equilibrium dynamics of many-body quantum systems under the effect of measurement protocols is attracting an increasing amount of attention. It has been recently revealed that measurements may


Inhomogeneous quantum quenches
We study the problem of a quantum quench in which the initial state is the ground state of an inhomogeneous Hamiltonian, in two different models, conformal field theory and ordinary free field
Entanglement evolution and generalised hydrodynamics: noninteracting systems
The large-scale properties of homogeneous states after quantum quenches in integrable systems have been successfully described by a semiclassical picture of moving quasiparticles. Here we consider
Spreading of entanglement and correlations after a quench with intertwined quasiparticles
We extend the semiclassical picture for the spreading of entanglement and correlations to quantum quenches with several species of quasiparticles that have non-trivial pair correlations in momentum
Quench dynamics and relaxation in isolated integrable quantum spin chains
We review the dynamics after quantum quenches in integrable quantum spin chains. We give a pedagogical introduction to relaxation in isolated quantum systems, and discuss the description of the

The time evolution of the entanglement entropy in non-equilibrium quantum systems provides crucial information about the structure of the time-dependent state. For quantum quench protocols, by

Nonequilibrium quantum dynamics and transport: from integrability to many-body localization
We review the non-equilibrium dynamics of many-body quantum systems after a quantum quench with spatial inhomogeneities, either in the Hamiltonian or in the initial state. We focus on integrable and
Time evolution of local observables after quenching to an integrable model.
This work argues that the behavior of local observables at late times after the quench is given by their expectation values with respect to a single representative Hamiltonian eigenstate, and presents a method for constructing this representative state by means of a generalized thermodynamic Bethe ansatz.
Hybrid Semiclassical Theory of Quantum Quenches in One-Dimensional Systems.
A hybrid semiclassical method to study the time evolution of one-dimensional quantum systems in and out of equilibrium by a modified time-evolving block decimation method while treating orbital quasiparticle motion classically is developed.
