论文摘要
关于单组玻色凝结液（BEC）中超偏度的最新研究依赖于Lee-huang-Yang（Lhy）校正自我结合的液滴的稳定，但是，这涉及液滴内部的高密度，从而限制了supersolid的寿命。在这里，我们提出了偶极性和非二极管BEC的两组分组的混合物，例如$^{166} $ er-$^{87} $ rb混合物，以创建和稳定无LHY校正的超固体，可以抑制原子损失，并可以抑制过时的动力学的长期动力学。在这样的系统中，可以通过两个组件之间的陷阱中心的差异来控制超验证。
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.
