Entanglement evolution and generalised hydrodynamics: interacting integrable systems
Vincenzo Alba, Bruno Bertini, Maurizio Fagotti
Izvirni znanstveni članek
Oznake:
We investigate the dynamics of bipartite entanglement after the sudden junction of two leads in interacting integrable models. By combining the quasiparticle picture for the entanglement spreading with Generalised Hydrodynamics we derive an analytical prediction for the dynamics of the entanglement ...

Nonequilibrium symmetry-protected topological order: emergence of semilocal Gibbs ensembles
Maurizio Fagotti, Vanja Marić, Lenart Zadnik
Izvirni znanstveni članek
Oznake: statistična fizika;neravnovesna statistična mehanika;statistical physics;nonequilibrium statistical mechanics;
We consider nonequilibrium time evolution in quantum spin chains after a global quench. Usually a nonequilibrium quantum many-body system locally relaxes to a (generalized) Gibbs ensemble built from conserved operators with quasilocal densities. Here we exhibit explicit examples of local Hamiltonian ...

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 the generalisation for the entanglement evolution after an inhomogeneous quench in noninteracting syste ...
