In this paper, we present a rigorous investigation of the quantum phase transitions (QPTs) for a model which describes the degenerate collective regime of a three-level V-configuration atoms Bose-Einstein condensate (BEC). We consider that the three-

We present a two-level atomic Bose–Einstein condensate (BEC) with dispersion, which is coupled to a high-finesse optical cavity. We call this model the extended Jaynes–Cummings–Dicke (JC-Dicke) model and introduce an effective Hamiltonian for t

We consider a general Hamiltonian for a system which consists of a three level lambda configuration atom interacting with a one-mode cavity field. Besides the intensity-dependent coupling the model includes multi-photon process as well as a non-linea

A system of N two-level atoms, Tavis-Cummings Dicke (TC-Dicke) model, interacting with a one-mode electromagnetic radiation field in the presence of the Stark shifts is studied, which is expected to predict new phenomena that are not explored in the

We study the interaction of a one-mode electromagnetic field with a three-level Λ-type atom in the presence of a classical homogeneous gravitational field. The atom and the field are initially prepared in the excited state and the coherent state, re
