朗道和利夫希茨1955年关于旋转超流体中涡面的论文几乎与费曼关于超流体中量子化涡的论文同时发表，但长期以来一直被认为是不正确的。40年后，作者的理论取得了胜利，Olli Lounasmaa低温实验室（Otaniemi，芬兰）的实验在旋转的低温恒温器中检测到了手性超流体中的涡面，验证了朗道和Lifshitz关于涡面分离和旋转角速度的方程。本文讨论了在超流中已经观察到或可能观察到的涡面构形。
Landau's and Lifshitz's 1955 paper on vortex sheets in a rotating superfluid came out almost simultaneously with Feynman's paper on quantized vortices in superfluid and was long considered incorrect. Forty years later, in what was a triumph for the authors' theory, experiments at the Olli Lounasmaa Low Temperature Laboratory (Otaniemi, Finland) detected vortex sheets in chiral superfluid in a rotating cryostat, validating Landau's and Lifshitz's equation relating the vortex sheet separation and the angular velocity of rotation. This paper discusses vortex sheet configurations that have been or can be observed in superfluid .
