Dynamics of Coherent States in Regular and Chaotic Regimes of the Non-integrable Dicke Model
S. Lerma-Hernández, J. Chávez-Carlos, M. A. Bastarrachea-Magnani +2
The quantum dynamics of initial coherent states is studied in the Dicke model and correlated with the dynamics, regular or chaotic, of their classical limit. Analytical expressions…
Comparative quantum and semi-classical analysis of Atom-Field Systems II: Chaos and regularity
M. A. Bastarrachea-Magnani, S. Lerma-Hernandez, J. G. Hirsch
The non-integrable Dicke model and its integrable approximation, the Tavis-Cummings (TC) model, are studied as functions of both the coupling constant and the excitation energy. Th…
Comparative quantum and semi-classical analysis of Atom-Field Systems I: density of states and excited-state quantum phase transitions
M. A. Bastarrachea-Magnani, S. Lerma-Hernandez, J. G. Hirsch
We study the non-integrable Dicke model, and its integrable approximation, the Tavis-Cummings model, as functions of both the coupling constant and the excitation energy. Excited-s…
