论文摘要
Rossby-Haurwitz（RH）波是旋转球面上流体的激发模式，它在旋转的参考框架中向西传播。由于最近在微重力中实现了壳形的玻色菌冷凝水的动机，我们研究了在球形表面几何形状上旋转的超氟中的RH波。我们采用点 - 涡流模型和三维的GROSS-PITAEVSKII方程，并数值证明可以在具有量化涡流的超流体系统中观察到RH波。
A Rossby-Haurwitz (RH) wave is an excitation mode of a fluid on a rotating spherical surface, which propagates westward in the rotating frame of reference. Motivated by the recent realization of the shell-shaped Bose-Einstein condensate in microgravity, we investigate the RH wave in a superfluid rotating on a spherical-surface geometry. We employ the point-vortex model and the three-dimensional Gross-Pitaevskii equation, and numerically demonstrate that RH waves can be observed in the system of a superfluid with quantized vortices.
