Critical behavior of dissipative two-dimensional spin lattices
R. Rota, F. Storme, N. Bartolo +2
We explore critical properties of two-dimensional lattices of spins interacting via an anisotropic Heisenberg Hamiltonian and subject to incoherent spin flips. We determine the ste…
Signatures of many-body localisation in the dynamics of two-sites entanglement
Fernando Iemini, Angelo Russomanno, Davide Rossini +2
We are able to detect clear signatures of dephasing -- a distinct trait of Many-Body Localisation (MBL) -- via the dynamics of two-sites entanglement, quantified through the concur…
Critical dynamical properties of a first-order dissipative phase transition
Wim Casteels, Rosario Fazio, Cristiano Ciuti
We theoretically investigate the critical properties of a single driven-dissipative nonlinear photon mode. In a well-defined thermodynamical limit of large excitation numbers, the…
Entanglement entropy in a periodically driven Ising chain
Angelo Russomanno, Giuseppe E. Santoro, Rosario Fazio
In this work we study the entanglement entropy of a uniform quantum Ising chain in transverse field undergoing a periodic driving of period . By means of Floquet theory we show…
