中文摘要：
运用线性熵和熵压缩理论,研究了缀饰态表象下驱动两能级原子和场相互作用系统的纠缠和原子熵压缩随时间的演化特性,讨论了数态光子数、原子与经典驱动场的耦合系数以及原子跃迁频率与经典驱动场频率失谐量对纠缠和熵压缩的影响。结果表明原子线性熵和熵压缩随时间的演化呈现周期性规律,线性熵的最大值随着数态光子数,原子与经典驱动场的耦合系数以及失谐量的增大而增大,并且通过调节原子与经典驱动场的耦合系数以及失谐量可以产生压缩度大、压缩时间长的原子熵压缩态,理论上提供了一种调控纠缠和熵压缩的方式。
英文摘要：
Using the theory of linear entropy and entropy squeezing, the dynamics of the entanglement and entropy squeezing of the atom driven by classical fields interacting with field by employing the dressed-state representation is examined. The influence of the photon number of Fock state, coupling coefficient of atoms and the classical driving field, and the detuning between atomic transition frequency and classical driving field frequency on the entanglement and entropy squeezing of the atom is discussed. It is shown that the evolution of linear entropy and entropy squeezing exhibits periodic behavior. The maximum value of the linear entropy increases as the photon number of Fock state, the coupling coefficient of atom and the classical driving field and the detuning increase. The high-degree squeezed and longtime atomic squeezing state can be created by controlling the coupling coefficient of atoms and the classical driving field and the detuning. The proposal may provide a theoretical way to control and manipulate the entanglement and entropy squeezing.
