论文摘要
SuperSolid是一种异国情调的物质状态，显示了具有超氟背景的结晶阶，最近在陷阱中观察到的偶极玻色 - 仁冷凝水（BEC）。在这里，我们介绍了所需的Bloch形式的精确溶液，以自我捕获的自由浮动量子流体。我们对经修订的非线性schr {Ö} dinger方程（管理平均场和均值场动力学）的一般解决方案是通过m {Ö} Bius变换获得的，将一类宽类的超olid溶液连接到无处不在的cNoidal波。该溶液在不同参数域中产生恒定的冷凝物，超old行为和自捕获的液滴。发现最低的残留冷凝物正好是恒定背景的三分之一。
Supersolid is an exotic state of matter, showing crystalline order with a superfluid background, observed recently in dipolar Bose-Einstein condensate (BEC) in a trap. Here, we present exact solutions of the desired Bloch form in the self-trapped free-floating quantum fluid. Our general solutions of the amended nonlinear Schr{ö}dinger equation, governing the mean-field and beyond mean-field dynamics, are obtained through a M{ö}bius transform, connecting a wide class of supersolid solutions to the ubiquitous cnoidal waves. The solutions yield the constant condensate, supersolid behavior and the self-trapped droplet in different parameter domains. The lowest residual condensate is found to be exactly one-third of the constant background.
