Enhancing entanglement asymmetry in fragmented quantum systems
Lorenzo Gotta, Filiberto Ares, Sara Murciano
Entanglement asymmetry provides a quantitative measure of symmetry breaking in many-body quantum states. Focusing on inhomogeneous charges, such as dipole and multipole mome…
Towers of quantum many-body scars under stochastic resetting
Lorenzo Gotta, Manas Kulkarni, Gabriele Perfetto
Towers of quantum many-body scars are sets of highly-excited eigenstates of nonintegrable Hamiltonians whose dynamics shows athermal behavior and persistent oscillations in time. T…
Open-system quantum many-body scars: a theory
Lorenzo Gotta
In this work, we undertake the problem of formally introducing a notion of quantum many-body scarring in open quantum systems governed by the Lindblad equation. To this goal, we re…
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…
