标题： Perturbative dissipation dynamics of a weakly driven Jaynes-Cummings system

摘要： 我们将微观主方程方法推广，以研究具有弱外场驱动的Jaynes-Cummings两能级系统的耗散动力学。通过摄动分析扩展阻尼基理论，我们解析地推导出校正后的拉比振荡和真空拉比劈裂。弱驱动系统去相干因子的演化表明，非对角密度矩阵元素除以一个依赖于驱动强度和初始反转率的频率振荡。对于弱驱动极限下的高度反转系统，此频率减小至非驱动系统值的两倍，这显示了无法用更传统的方法发现的耗散动力学。 显示英文摘要

摘要： We generalize a microscopic master equation method to study the dissipation dynamics of Jaynes-Cummings two-level system with a weak external driving. Using perturbative analysis to extend the damping bases theory, we derive the corrected Rabi oscillation and vaccum Rabi splitting analytically. The evolution of the decoherence factor of the weakly driven system reveals that the off-diagonal density matrix elements are oscillating at a frequency dependent on the driving strength and the initial population inversion. For highly-inverted systems at the weak-driving limit, this frequency reduces to twice the value for the non-driven system, showing the dissipation dynamics unable to be discovered using more conventional approaches.
