Abstract
We investigate nonlocal correlations between a three-level atom and the optical field initially being in the photon-added squeezed thermal state. We examine the effect of the squeezing parameter and the number of added photons to the squeezed thermal field on the entanglement during the time evolution. We show that the entanglement can be enhanced by increasing the number of added photons and the squeezing parameter for moving and nonmoving three-level atoms. We present a useful way to generate and restrain a large amount of entanglement by increasing the number of added photons when the atomic motion is described by the atomic velocity.
