环阱中两组分玻色-爱因斯坦凝聚体的转动响应

Rotational Response of Two-Component Bose-Einstein Condensates in Ring Traps

P. L. Halkyard, M. P. A. Jones, S. A. Gardiner

摘要:

我们考虑一个两个组件的玻色-爱因斯坦凝聚体(BEC)在一个旋转的框架中的环形陷阱,并显示如何确定这样的配置的响应是在一个旋转的框架中,通过积累的Sagnac相。这可以通过粒子数振荡或空间密度条纹的运动来实现。我们明确地包括通过平均场描述的相互作用的效果,并研究相对于一个理想的配置的动态保真度。

英文摘要:

We consider a two-component Bose-Einstein condensate (BEC) 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 either through 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.
