Observing weakly broken conservation laws in a dipolar Rydberg quantum spin chain
Cheng Chen, Luca Capizzi, Alice Marché +6
Integrable quantum many-body systems host families of extensive conservation laws, some of which are fragile: even infinitesimal perturbations can qualitatively alter their dynamic…
Ergodicity and hydrodynamics: from quantum to classical spin systems
Jiaozi Wang, Luca Capizzi, Dario Poletti +1
We show that in classical spin systems the precise nature of the late-time hydrodynamic tails of the autocorrelation functions of a generic observable is determined by (i) the dyna…
Transport in a System with a Tower of Quantum Many-Body Scars
Gianluca Morettini, Luca Capizzi, Maurizio Fagotti +1
We report the observation of unconventional transport phenomena in a spin-1 model that supports a tower of quantum many-body scars, and we discuss their properties uncovering their…
Exceptional stationary state in a dephasing many-body open quantum system
Alice Marché, Gianluca Morettini, Leonardo Mazza +2
We study a dephasing many-body open quantum system that hosts, together with the infinite-temperature state, another additional stationary state. The latter is exceptional in many…
