Dynamical correlation functions of extensive charges after global quantum quenches
Riccardo Travaglino, Katja Klobas, Bruno Bertini +1
We investigate the -time cumulant generating function (or -Full Counting Statistics, -FCS) of extensive charges following a quantum quench. Exploiting space-time du…
Athermality of generalized Gibbs ensembles
Riccardo Senese, Bruno Bertini, Katja Klobas +1
Integrable quantum systems evolving from non-equilibrium initial states do not thermalize to conventional Gibbs ensembles (GE). Instead, at long times they relax to generalized Gib…
Space-time duality approach to (inhomogeneous) integrable quenches
Riccardo Travaglino, Pasquale Calabrese, Katja Klobas +1
Characterising the universal aspects of non-equilibrium quantum many-body dynamics is one of the key goals of this century's physics research. Progress, however, is hindered by the…
Low Rank Structure of the Reduced Transition Matrix
Cathy Li, Bruno Bertini, Katja Klobas +1
The influence-matrix formalism provides an alternative route to the classical simulation of quantum dynamics. Because influence matrices retain information only about the effective…
