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…
Topological phases in odd-legs frustrated synthetic ladders
S. Barbarino, M. Dalmonte, R. Fazio +1
The realization of the Hofstadter model in a strongly anisotropic ladder geometry has now become possible in one-dimensional optical lattices with a synthetic dimension. In this wo…
Linked cluster expansions for open quantum systems on a lattice
Alberto Biella, Jiasen Jin, Oscar Viyuela +3
We propose a generalization of the linked-cluster expansions to study driven-dissipative quantum lattice models, directly accessing the thermodynamic limit of the system. Our metho…
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…
Direct comparison of quantum and simulated annealing on a fully-connected Ising ferromagnet
Matteo M. Wauters, Rosario Fazio, Hidetoshi Nishimori +1
We compare the performance of quantum annealing (QA, through Schrödinger dynamics) and simulated annealing (SA, through a classical master equation) on the -spin infinite range…
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…
