Quantum many-body scars leading to time-translation symmetry breaking in kicked interacting spin models
Ángel L. Corps, Armando Relaño, Angelo Russomanno
We study an Ising model with long-range interactions undergoing a time-periodic kicking. For different initial states we observe persistent period doubling. When there is period do…
Spatiotemporally ordered patterns in a chain of coupled dissipative kicked rotors
Angelo Russomanno
In this work we consider the dynamics of a chain of many coupled kicked rotors with dissipation. We map a rich phase diagram with many dynamical regimes. We focus mainly on a regim…
Entanglement dynamics with string measurement operators
Giulia Piccitto, Angelo Russomanno, Davide Rossini
We explain how to apply a Gaussian-preserving operator to a fermionic Gaussian state. We use this method to study the evolution of the entanglement entropy of an Ising spin chain f…
Weak ergodicity breaking in Josephson-junction arrays
Angelo Russomanno, Michele Fava, Rosario Fazio
We study the quantum dynamics of Josephson junction arrays. We find isolated groups of low-entanglement eigenstates, that persist even when the Josephson interaction is strong enou…
Quantum chaos and ensemble inequivalence of quantum long-range Ising chains
Angelo Russomanno, Michele Fava, Markus Heyl
We use large-scale exact diagonalization to study the quantum Ising chain in a transverse field with long-range power-law interactions decaying with exponent . We numerically st…
Quantum clock models with infinite-range interactions
Adu Offei-Danso, Federica Maria Surace, Fernando Iemini +2
We study the phase diagram, both at zero and finite temperature, in a class of models with infinite range interactions. We are able to identify the transitions betwe…
