实验研究了双向非对称泵浦光学环形腔中玻色-爱因斯坦凝聚体的动态不稳定性。我们发现，在超过临界谐振腔-泵浦失谐后，系统变得稳定，而与泵浦强度无关。给出了相图和淬火曲线，并用数值模拟进行了描述。我们讨论了一种基于对基本的非线性运动方程的几何解释的物理解释。
We experimentally investigate the dynamic instability of Bose-Einstein condensates in an optical ring resonator that is asymmetrically pumped in both directions. We find that, beyond a critical resonator-pump detuning, the system becomes stable regardless of the pump strength. Phase diagrams and quenching curves are presented and described by numerical simulations. We discuss a physical explanation based on a geometric interpretation of the underlying nonlinear equations of motion.
