QUANTUM TREATMENT FOR TWO TWO-LEVEL ATOMS IN INTERACTION WITH AN SU(1,1) QUANTUM SYSTEM

摘要

We consider the interaction between two identical two-level atoms prepared in superposition states and an SU(1,1) quantum system prepared in the Perelemov coherent state. We determine the time-dependent wave function through the Schrodinger equation for the resonance case, and, consequently, we obtain the density matrix. We consider the phenomenon of collapses and revivals of the atomic population inversion for different values of the parameters and show the coherent trapping. We investigate the entanglement in the system where we discuss the linear entropy for different values of the involved parameters and for some states. Finally we examine the second-order correlation function to distinguish between the classical and nonclassical behaviors. We show that the system is sensitive to the variation in both the Bargmann index k and the Perelomov coherent parameter μ, as well as the atomic phase parameters.
