我们考虑了一个双组分玻色-爱因斯坦凝聚态在旋转框架中的环阱，并展示了如何通过Sagnac相的积累来确定这种构型对旋转框架的响应。这可以通过种群振荡或空间密度条纹的运动来实现。我们通过平均场描述明确地包括了相互作用的影响，并研究了相对于理想构型的动力学保真度。
We consider a two-component Bose-Einstein condensate in a ring trap in a rotating frame and show how to determine the response of such a configuration to being in a rotating frame via accumulation of a Sagnac phase. This may be accomplished through either population oscillations or the motion of spatial-density fringes. We explicitly include the effect of interactions via a mean-field description and study the fidelity of the dynamics relative to an ideal configuration.
