Comparative quantum and semiclassical analysis of atom-field systems. II. Chaos and regularity
Comparative quantum and semiclassical analysis of atom-field systems. II. Chaos and regularity
The nonintegrable Dicke model and its integrable approximation, the Tavis-Cummings model, are studied as functions of both the coupling constant and the excitation energy. The present contribution extends the analysis presented in the previous paper by focusing on the statistical properties of the quantum fluctuations in the energy spectrum and …
