摘　　要：研究了两能级发射体与振动石墨烯薄膜相互作用系统中熵压缩性质,讨论了相干角,两能级发射体与振动石墨烯薄膜之间的耦合系数和两能级发射体的跃迁频率与驱动场频率的失谐量以及相干性对两能级发射体熵压缩的影响,结果表明:通过调节相干角,两能级发射体与机械振子的耦合系数和两能级发射体的跃迁频率与驱动场频率的失谐量可以制备两能级发射体最佳熵压缩态.理论上提供了一种调控两能级发射体耦合石墨烯机械振子系统中熵压缩的方式.In this paper,the entropy squeezing of the two-level emitter interacting with vibrating graphene membrane system was investigated.The effects of coherence angle,the coupling coefficient between two-level emitter and the vibrating graphene membrane,and detuning between the transition frequency of two-level emitter and the driving field frequency on the entropy squeezing are analyzed.It is shown that the optimal entropy squeezed state can be generated by controlling the coherence angle,the coupling coefficient between two-level emitter and the vibrating graphene membrane,and the detuning between the transition frequency of two-level emitter and the driving field frequency.The proposal may provide a theoretical way to manipulate entropy squeezing of the two-level emitter in the system.
