Effects of squeezing parameter and time dependent coupling on the evalution of the entanglement between two -level atoms
In this article we consider the interaction between two two-level atoms and a squeezed field mode. The atom-atom entanglement is discussed by the evolution of the concurrence. von Neumann entropy is used for studying the dynamical behavior of the nonlocal correlation between the squeezed field and two atoms. It is found that the squeeze parameter, atomic motion though the velocity ... إقراء المزيد
