The full Dicke model describes a system of N identical two level-atoms coupled to a single mode quantized bosonic field. The model considers rotating and counter-rotating coupling terms between the atoms and the bosonic ...

An intensity dependent nonlinear coupling model of N two-level atoms (generalized Dicke model) interacting dispersively with a bimodal cavity field via two-photon transitions is investigated in a scenario where the rotating ...

Using the «gap equations», we calculate the thermodynamic properties of the models A, B, C considered by Hioe as well as the Dicke model modified by acoustic phonons according to Thompson. © 1975 Società Italiana di Fisica.

By means of the use of the gap equations, we calculate the thermodynamic properties of a sufficiently general Dicke model. We obtain the general relations which correspond to the condition of second-order phase transition ...

We apply the Gauss-Codazzi formalism to brane-worlds within the framework of Brans-Dicke gravity. The compactification is taken from six to five dimensions in order to formalize brane-world models with hybrid compactification ...
