In this paper, the
entanglement between two atoms and squeezed field via four photon process is
investigated. The dynamical behavior of the entanglement between two atoms and
a squeezed field is analyzed. In particular, the effects of the atomic motion,
the initial atomic state and the field squeezing are examined. A high amount of
entanglement is generated by increasing the field squeezing. Furthermore, we
show that a sudden death and sudden birth emerge when the moving atoms are
initially prepared in the excited state.
