Abstract

我们在由二光子的微波地联合的二部件的鲍斯·爱因斯坦冷凝物调查局部性的原子事波浪。有趣地，局部性的原子事波浪的摆动将逐渐地腐烂并且就算存在联合地，最后成为不振荡的行为。特别地，在二不同亢奋的罚款占据的原子数字旋转状态将显得不对称职业过了一会儿进化。

Localized Asymmetric Atomic Matter Waves in Two-Component Bose–Einstein Condensates Coupled with Two-Photon Microwave Field

Bo Xiong

We investigate localized atomic matter waves in two-component Bose–Einstein condensates coupled by the two-photon microwave field. Interestingly, the oscillations of localized atomic matter waves will gradually decay and finally become non-oscillating behavior even if existing coupling field. In particular, atom numbers occupied in two different hyperfine spin states will appear asymmetric occupations after some time evolution.

Multistability in an optomechanical system with a two-component Bose-Einstein condensate

Ying Dong, Jinwu Ye, Han Pu

We investigate a system consisting of a two-component Bose-Einstein condensate interacting dispersively with a Fabry-Perot optical cavity where the two components of the condensate are resonantly coupled to each other by another classical field. The key feature of this system is that the atomic motional degrees of freedom and the internal pseudospin degrees of freedom are coupled to the cavity field simultaneously, hence an effective spin-orbital coupling within the condensate is induced by the cavity. The interplay among the atomic center-of-mass motion, the atomic collective spin, and the cavity field leads to a strong nonlinearity, resulting in multistable behavior in both matter wave and light wave at the few-photon level.
