Abstract: We present a detailed study of the behavior of the delocalization properties in the phase space of the Husimi function of ground and excited states in the avoided crossings vicinity for a Hamiltonian of Lipkin–Meshkov–Glick… read more here.

Abstract: We derive a Lindblad master equation that approximates the dynamics of a Lipkin-Meshkov-Glick (LMG) model weakly coupled to a bosonic bath. By studying the time evolution of operators under the adjoint master equation we prove… read more here.

DOI: 10.1103/physrevb.101.054431
Abstract: Correlations play a key role in critical phenomena. Quantities such as the entanglement entropy, for instance, provide key insights into the mechanisms underlying quantum criticality. Almost all of our present knowledge, however, is restricted to… read more here.
