摘要:

通过改变~(87)Rb原子的内部状态,使具有畴结构的不混溶凝聚体转变为混溶凝聚体,从而激发了双组分玻色-爱因斯坦凝聚体的非平衡空间动力学.随后的演变表现出振荡的空间结构,涉及组分的混合和分离。结果表明,混溶体系的总能量越大,振荡频率越高。本文介绍了一种控制原子玻色-爱因斯坦凝聚体的扩散率和空间自由度的新方法。

英文摘要:

The non-equilibrium spatial dynamics in a two-component Bose-Einstein condensate were excited by controlled miscible-immiscible transition, in which immiscible condensates with domain structures are transferred to the miscible condensates by changing the internal state of 87Rb atoms. The subsequent evolution exhibits the oscillation of spatial structures involving component mixing and separation. We show that the larger total energy of the miscible system results in a higher oscillation frequency. This investigation introduces a new technique to control the miscibility and the spatial degrees of freedom in atomic Bose-Einstein condensates.
