双组分偶极玻色-爱因斯坦凝聚体中的长寿命超固体

Long lifetime supersolid in a two-component dipolar Bose-Einstein condensate

Shaoxiong Li, Uyen Ngoc Le, Hiroki Saito

摘要:

最近对单组分玻色-爱因斯坦凝聚体(BEC)超固体性的研究依赖于Lee-Huang-Yang(LHY)修正来稳定自结合液滴,然而这涉及到液滴内部的高密度,限制了超固体的寿命。在这里,我们提出了一个双组分的混合物的偶极和非偶极BEC,如$^{166}$ Er- $^{87}$ Rb混合物,创建和稳定的超固体没有LHY校正,它可以抑制原子的损失,并可能允许观察的超固体的长时间动力学。在这样的系统中,超固态可以通过两个组分之间的陷阱中心的差异来控制。

英文摘要:

Recent studies on supersolidity in a single-component Bose-Einstein condensate (BEC) have relied on the Lee-Huang-Yang (LHY) correction for stabilization of self-bound droplets, which however involves a high density inside the droplets, limiting the lifetime of the supersolid. Here we propose a two-component mixture of dipolar and nondipolar BECs, such as an $^{166}$Er-$^{87}$Rb mixture, to create and stabilize a supersolid without the LHY correction, which can suppress the atomic loss and may allow observation of the long-time dynamics of the supersolid. In such a system, supersolidity can be controlled by the difference in the trap centers between the two components.
