Entanglement and decoherence in the interaction between two-mode squeezing vacuum state field and atom
双模压缩真空态与原子相互作用中的量子纠缠和退相干

Considering the interaction between two\|mode squeezing vacuum state field and environment(atom), we investigate the entanglement of field\|atom and one of two modes of field using the quantum reduced entropy and quantum relative entropy, respectively.
