Abstract We consider a theoretical scheme for entanglement transfer between a two-mode squeezed vacuum field and two initially separable atoms through intensity-dependent couplings. We find that the entanglement transfer between the field and the atoms has an exact period for any given squeezing. We also find that the maximum achievable entanglement of the atomic subsystem is a simple increasing function of r. For sufficiently large squeezing parameter r, it is possible for the atoms to be entangled into a
Bell state at half the periodic time points.
