Effect of the Atomic Dipole-Dipole Interaction on the Phase Diagrams of 2-Level Matter-Field Systems
S. Cordero, E. Nahmad-Achar, O. Castaños +1
Quantum information measures are used to study the quantum phase diagrams of a two-level extended Dicke model, including the particle dipole-dipole interaction, for a finite number…

Wigner Function Analysis of Finite Matter-Radiation Systems
E. Nahmad-Achar, R. López-Peña, S. Cordero +1
We show that the behaviour in phase space of the Wigner function associated to the electromagnetic modes carries the information of both, the entanglement properties between matter…
