Entropy of entanglement between quantum phases of a three-level matter-radiation interaction model
Luis Fernando Quezada, Eduardo Nahmad-Achar
We show that the entropy of entanglement is sensitive to the coherent quantum phase transition between normal and super-radiant regions of a system of a finite number of three-leve…

Characterization of the quantum phase transition in a two-mode Dicke model for different cooperation numbers
L. F. Quezada, E. Nahmad-Achar
We show how the use of variational states to approximate the ground state of a system can be employed to study a multi-mode Dicke model. One of the main contributions of this work…
