| Summary: | Recent successfull experimental realization of the Dicke Model with a time rependent coupling parameter, have draw the attention in the study of dynamical properties present in the Light-matter interaction model. Althoug some research on the non-equilibrium model has been presented, a rather knew QPT known as Excited Stated Quantum Phase Trasnition had not been studied previously. Here we present the dynamical study of the DM where the coupling parameter follows a triangular dependance with time. We show that the change in estatistic of the ground state fidelity and the appearance of finite occupation for cases values of the coupling parameter implies the apperance of the ESQPT in the dynamic model |
