Non-adiabatic breaking of topological pumping
Lorenzo Privitera, Angelo Russomanno, Roberta Citro +1
We study Thouless pumping out of the adiabatic limit. Our findings show that despite its topological nature, this phenomenon is not {generically} robust to non-adiabatic effects. I…
From localization to anomalous diffusion in the dynamics of coupled kicked rotors
Simone Notarnicola, Fernando Iemini, Davide Rossini +3
We study the effect of many-body quantum interference on the dynamics of coupled periodically kicked systems whose classical dynamics is chaotic and shows an unbounded energy incre…
Boundary time crystals
F. Iemini, A. Russomanno, J. Keeling +3
In this work we introduce {\it boundary time-crystals}. Here {\it continuous} time-translation symmetry breaking occurs only in a macroscopic fraction of a many-body quantum system…
Resilience of hidden order to symmetry-preserving disorder
Marcello Calvanese Strinati, Davide Rossini, Rosario Fazio +1
We study the robustness of non-local string order in two paradigmatic disordered spin-chain models, a spin-1/2 cluster-Ising and a spin-1 XXZ Heisenberg chain. In the clean case, t…
Floquet resonances close to the adiabatic limit and the effect of dissipation
Angelo Russomanno, Giuseppe E. Santoro
We study the approach to the adiabatic limit in periodically driven systems. Specifically focusing on a spin-1/2 in a magnetic field we find that, when the parameters of the Hamilt…
Floquet time crystal in the Lipkin-Meshkov-Glick model
Angelo Russomanno, Fernando Iemini, Marcello Dalmonte +1
In this work we discuss the existence of time-translation symmetry breaking in a kicked infinite-range-interacting clean spin system described by the Lipkin-Meshkov-Glick model. Th…
Multipartite entanglement after a quantum quench
Silvia Pappalardi, Angelo Russomanno, Alessandro Silva +1
We study the multipartite entanglement of a quantum many-body system undergoing a quantum quench. We quantify multipartite entanglement through the quantum Fisher information (QFI)…
