Dependence of the Superfluidity Criterion on the Capillary Radius
V. P. Maslov M. V. Lomonosov Moscow State University, Faculty of Physics
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 $L_2$. If the velocity of a superfluid liquid exceeds $8\pi\hbar/(mL_2)$, then it brakes because of the friction against the eddy formed by pairs (similar to the pairs in the Andreev reflection).
Keywords:
superfluidity, ultrasecond quantization, thermodynamic limit, quasiparticle spectrum, capillary thickness, eddy.
