Asymptotically exact solution of the generalized Dicke model
I. G. Brankov, V. A. Zagrebnov, N. S. Tonchev
Abstract:
The exact solution for the generalized Dicke model is obtained by using a modification
of the method of N. N. Bogoliubov (Jr.). Thermodynamics of the boson and spin
subsystems is studied. It is shown that the initial system containing interaction with
a boson field is thermodynamically equivalent to an anisotropic $X$–$Y$-model with infinitely
long range of interaction.
