Abstract

We present a theoretical scheme for generating spin squeezed state of atom-photon in atomic Bose-Einstein condensate(BEC) via electromagnetically induced transparency(EIT). Here we focus on the influence of the laser-atom dipole interaction and the two-photon detuning on the degree of spin squeezing. The stronger laser-atom dipole interaction and the smaller two-photon detuning more rapidly induces the stronger spin squeezing.
