摘要

我们考虑了在法布里-珀罗腔内通过辐射压力与光场耦合的冷原子动力学。我们观察了改变原子团的有效定位对冷原子有效机械频率和阻尼率的影响。我们进一步研究了原子振荡器的位移谱，并分析了正常模式分裂为两种模式的情况。我们主要分析了原子团的位置如何作为一种额外工具，显著改变原子与空腔场的相互作用强度。本方案有助于进一步研究如何连贯地控制冷原子的动力学。

Effect of atomic ensemble position on the dynamics of cold atoms in an optical cavity: normal-mode splitting

We consider the dynamics of cold atoms coupled to the light field via radiation pressure within a Fabry-Perot cavity. We observe the effects of changing the effective positioning of the atomic ensemble on the effective mechanical frequency and the damping rate of cold atoms. We further study the displacement spectrum of the atomic oscillator and analyze the occurrence of normal mode splitting into two modes. We mainly analyze how the position of the ensemble acts as an additional tool in significantly altering the atomic and cavity field interaction strength. The present scheme enables further studies of coherently controlling the dynamics of the cold atoms.
