✦ Synopsis

We stud,y phase properties of generalized coherent states obtained from usual Fock coherent states by adapting classical methods of statistical mechanics, in particular, the well-known procedure of thermodynamical limit. Moreover, we show that there exists a close connection between these states and the states describing boson systems with condensation properties.

We study the thermodynamical property of a Dicke model with classical spin. As in the quantum case, the model exhibits a phase transition associated with the spontaneous breaking of the gauge symmetry. We calculate the thermodynamical equilibrium photon state in a relatively simple way both at any t
