论文摘要
我们通过伪粒子代表中的Keldysh图技术介绍了Bissable驱动系统的荧光光谱的分析和数值研究。光谱在超量子和准经典极限之间表现出平滑的跃迁，并指示发生最可能的稳定状态时外部场的阈值。荧光光谱的分析还允许确定系统中最可能的稳定状态。还表明，在整数和半级吸引人的非核度比率多光子共振导致荧光光谱的突然变化。还发现，荧光光谱在零环境温度的极限下是对称的。在微波或光学结构域中使用超高质量谐振器的实验中，可以观察到光谱的预测特征。
We present an analytical and numerical study of the fluorescence spectra of a bistable driven system by means of Keldysh diagram technique in pseudo--particle representation. The spectra exhibit smooth transition between ultra-quantum and the quasiclassical limits and indicate the threshold value of the external field when changing of the most probable stable state occurs. The analysis of the fluorescence spectra also allows to determine the most probable stable state of the system. It was also shown that at integer and half-integer detuning-nonlinearity ratio multiphoton resonance leads to abrupt changes in fluorescence spectra. It was also revealed that the fluorescence spectra are symmetric in the limit of zero environment temperature. The predicted features of the spectra could be observed in experiments with ultra-high quality resonators in either microwave or optical domain.
