Abstract:
We replace the conditions on the capillary boundary with the Born–Karman periodic conditions, i. e., we consider a two-dimensional torus of radius L2. If the velocity of a superfluid liquid exceeds 8πℏ/(mL2), then it brakes because of the friction against the eddy formed by pairs (similar to the pairs in the Andreev reflection).
