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…

Exact subsystem dynamics in the deterministic Floquet-PXP model

Katja Klobas

The dynamics of local subsystems in a thermodynamically large quantum many-body system can be understood as effectively open as the system produces its own effective bath. The acti…

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…

Initial State Memory in Finite Random Brickwork Circuits

Jakob Bannister, Katja Klobas, Colin Rylands +1

We ask under what conditions a finite brickwork circuit of random gates retains local information about the initial state. To answer this question we measure the averaged Frobenius…
