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…
A closed system setting for quantum thermalisation in free fermions
Purvaash Panduranghan-Udhayashankar, Filiberto Ares, Pasquale Calabrese
We study thermalisation and the possible occurrence of the Mpemba effect in a closed quantum setting that mimics the interaction of a system with thermal reservoirs coupled only at…
Double-weak-link interferometer of hard-core bosons in one dimension
A. Takacs, J. Dubail, P. Calabrese
We study the dynamics of a lattice hard-core boson gas released from a domain wall initial state in the presence of two weak links (defects). When the two defects are separated by…
One-body correlations and momentum distributions of trapped one-dimensional Bose gases at finite temperature
Attila Takács, Yicheng Zhang, Pasquale Calabrese +3
We introduce a general approximate method for calculating the one-body correlations and the momentum distributions of one-dimensional Bose gases at finite interaction strengths and…
