Dynamical properties in the system of two identical two-level entangled atoms interacting with radiation fields in binomial states

In this article, the dynamical properties in the system of two identical two-le vel entangled atoms interacting with a binomial optical field are studied by mea ns of time evolution operator and numerical calculations. The results show that the time evolution of atomic population and atomic dipole squeezing depends on t he degree of entanglement of the initial two identical two-level entangled atom s and the parameters of the binomial state optical field. The atomic dipole mome nt can be completely squeezed via choosing appropriate parameters of the system.
