Dynamics of charge fluctuations from asymmetric initial states
Bruno Bertini, Katja Klobas, Mario Collura +2
Conserved-charge densities are very special observables in quantum many-body systems as, by construction, they encode information about the dynamics. Therefore, their evolution is…

Non-equilibrium entanglement asymmetry for discrete groups: the example of the XY spin chain
Florent Ferro, Filiberto Ares, Pasquale Calabrese
The entanglement asymmetry is a novel quantity that, using entanglement methods, measures how much a symmetry is broken in a part of an extended quantum system. So far it has only…
