Hybrid Quantum Entanglement Between Bose-Einstein Condensate and Light Field

We propose a scheme to prepare a hybrid entangled state of a Bose-Einstein condensate and an optical field. We calculate two entanglement parameters using the bosonization method. It shows that the hybrid entangled state can be prepared in the dynamic process. It also shows that the more entanglement can be realized by decreasing the linear coupling strength.
