Kitaev ring threaded by a magnetic flux: Topological gap, Anderson localization of quasiparticles, and divergence of supercurrent derivative
Martina Minutillo, Procolo Lucignano, Gabriele Campagnano +1
We study a superconducting Kitaev ring pierced by a magnetic flux, with and without disorder, in a quantum ring configuration, and in a rf-SQUID one, where a weak link is present.…
Non-ergodic behaviour of clean Bose-Hubbard chains
Angelo Russomanno, Michele Fava, Rosario Fazio
We study ergodicity breaking in the clean Bose-Hubbard chain for small hopping strength. We see the existence of a non-ergodic regime by means of indicators as the half-chain entan…
Discrete truncated Wigner approach to dynamical phase transitions in Ising models after a quantum quench
Reyhaneh Khasseh, Angelo Russomanno, Markus Schmitt +2
By means of the discrete truncated Wigner approximation we study dynamical phase transitions arising in the steady state of transverse-field Ising models after a quantum quench. St…
Many-body dynamical localization in the kicked Bose-Hubbard chain
Michele Fava, Rosario Fazio, Angelo Russomanno
We provide evidence that a clean kicked Bose-Hubbard model exhibits a many-body dynamically localized phase. This phase shows ergodicity breaking up to the largest sizes we were ab…
Slow heating in a quantum coupled kicked rotors system
Simone Notarnicola, Alessandro Silva, Rosario Fazio +1
We consider a finite-size periodically driven quantum system of coupled kicked rotors which exhibits two distinct regimes in parameter space: a dynamically-localized one with kinet…
Homogeneous Floquet time crystal protected by gauge invariance
Angelo Russomanno, Simone Notarnicola, Federica Maria Surace +3
We show that homogeneous lattice gauge theories can realize nonequilibrium quantum phases with long-range spatiotemporal order protected by gauge invariance instead of disorder. We…
Dissipation assisted Thouless pumping in the Rice-Mele model
Luca Arceci, Lucas Kohn, Angelo Russomanno +1
We investigate the effect of dissipation from a thermal environment on topological pumping in the periodically-driven Rice-Mele model. We report that dissipation can improve the ro…
Floquet time crystals in clock models
Federica Maria Surace, Angelo Russomanno, Marcello Dalmonte +3
We construct a class of period--tupling discrete time crystals based on clock variables, for all the integers . We consider two classes of systems where this p…
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…
Spin and topological order in a periodically driven spin chain
Angelo Russomanno, Bat-el Friedman, Emanuele G. Dalla Torre
The periodically driven quantum Ising chain has recently attracted a large attention in the context of Floquet engineering. In addition to the common paramagnet and ferromagnet, th…
Non equilibrium phase transitions and Floquet Kibble-Zurek scaling
Angelo Russomanno, Emanuele G. Dalla Torre
We study the slow crossing of non-equilibrium quantum phase transitions in periodically-driven systems. We explicitly consider a spin chain with a uniform time-dependent magnetic f…
