摘要：
We investigate a double-Lambda atomic ensemble trapped in a cavity and deduce the five species of polaritons. By analysing the analytic expression, we show the exchange of the two mode fields as well as frequency conversion. By studying the entanglement between the two mode fields, we exhibit the role of the five species of polaritons in entanglement creation. We also show the influence of the field and atomic decay on entanglement.
