研究了玻色-爱因斯坦凝聚体与单纵模超高精细驻波光谐振腔的光-机械相互作用。作为一种独特的特性，这种谐振器结合了三个以前没有一起实现的极端模式，即强合作耦合、珀塞尔因子远高于1的腔主导散射以及由小于单光子反冲频率四倍的腔阻尼率提供的亚反冲分辨率。我们给出的实验观测结果与一个双模模型很好地吻合，该模型预测了具有双稳、滞后、持续振荡和超辐射背向散射不稳定性特征的高度非线性动力学。
We study the optomechanical interaction of a Bose–Einstein condensate with a single longitudinal mode of an ultra-high finesse standing wave optical resonator. As a unique feature the resonator combines three extreme regimes, previously not realized together, ie, strong cooperative coupling, cavity dominated scattering with a Purcell factor far above unity, and sub-recoil resolution provided by a cavity damping rate smaller than four times the single photon recoil frequency. We present experimental observations in good agreement with a two-mode model predicting highly nonlinear dynamics with signatures as bistability, hysteresis, persistent oscillations, and superradiant back-scattering instabilities.
