[HTML][HTML] Quantum dynamics of a BEC interacting with a single-mode quantized field in the presence of interatom collisions
E Ghasemian, MK Tavassoly - Physics Letters A, 2016 - Elsevier
In this paper, we consider a model in which N two-level atoms in a Bose–Einstein
condensate (BEC) interact with a single-mode quantized laser field. Our goal is to
investigate the quantum dynamics of atoms in the BEC in the presence of interatom
interactions. To achieve the purpose, at first, using the collective angular momentum
operators, we try to reduce the dynamical Hamiltonian of the system to a well-known Jaynes–
Cummings like model (JCM). We also use the Dicke model to construct the state of atomic …
