Prethermalization and thermalization in entanglement dynamics
Bruno Bertini, Pasquale Calabrese
Izvirni znanstveni članek
Oznake: neravnovesna statistična mehanika;prepletenostna entropija;nonequilibrium statistical mechanics;entanglement entropy;
We investigate the crossover of the entanglement entropy toward its thermal value in nearly integrable systems. We employ equations-of-motion techniques to study the entanglement dynamics in a lattice model of weakly interacting spinless fermions after a quantum quench. For weak enough interactions ...

Entanglement and diagonal entropies after a quench with no pair structure
Bruno Bertini, Elena Tartaglia, Pasquale Calabrese
Izvirni znanstveni članek
Oznake: kvantna statistična mehanika;integrabilni sistemi;kvantna prepletenost;quantum statistical mechanics;integrable systems;quantum entanglement;
A typical working condition in the study of quantum quenches is that the initial state produces a distribution of quasiparticle excitations with an opposite-momentum-pair structure. In this work we investigate the dynamical and stationary properties of the entanglement entropy after a quench from in ...

Entanglement evolution and generalised hydrodynamics: noninteracting systems
Bruno Bertini, Maurizio Fagotti, Lorenzo Piroli, Pasquale Calabrese
Izvirni znanstveni članek
Oznake: neravnovesna dinamika;večdelčni sistemi;kvantna prepletenost;kvantni transport;non-equilibrium dynamics;many-body systems;quantum entanglement;quantum transport;
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 ...

Spin-charge separation effects in the low-temperature transport of one-dimensional Fermi gases
Márton Mestyán, Bruno Bertini, Lorenzo Piroli, Pasquale Calabrese
Izvirni znanstveni članek
Oznake: neravnovesna statistična mehanika;kvantna statistična mehanika;Fermijev plin;nonequilibrium statistical mechanics;quantum statistical mechanics;Fermi gas;
We study the transport properties of a one-dimensional spinful Fermi gas, after a junction of two semi-infinite subsystems held at different temperatures. The ensuing dynamics is studied by analyzing the space-time profiles of local observables emerging at large distances x and times t, as a functio ...
