论文摘要
我们考虑了通过各向同性三维谐波陷阱中的接触相互作用与第三个可区分的粒子相互作用的两个相同质量相同的系统的系统。我们计算系统以S波散射长度淬灭后的时间依赖性可观察结果。为此，我们使用精确的闭合形式的质量损伤性超球形解决方案来解决静态三体问题。这些精确的解决方案使我们能够计算两个时间依赖的可观察到的Ramsey信号和粒子分离，此前系统经历了从非相互作用到统一制度或反之亦然的淬火。
We consider a system of two identical fermions of general mass interacting with a third distinguishable particle via a contact interaction within an isotropic three-dimensional harmonic trap. We calculate time-dependent observables of the system after it is quenched in s-wave scattering length. To do this we use exact closed form mass-imbalanced hyperspherical solutions to the static three-body problem. These exact solutions enable us to calculate two time-dependent observables, the Ramsey signal and particle separation, after the system undergoes a quench from non-interacting to the unitary regime or vice-versa.
