We focus on numerical study of the dynamical Ginzburg-Landau equations under the temporal gauge, and propose a decoupled numerical scheme based on the finite element method. For the variable A, the se...
Scale-Separation Scheme for Simulating Superfluid Turbulence: Kelvin-Wave Cascade
Kelvin from the distorted wave of vortex superfluid turbulence low temperature the numerical simulation of vortex line
2014/12/20
A Kolmogorov-type cascade of Kelvin waves—the distortion waves on vortex lines—plays a key part in the relaxation of superfluid turbulence at low temperatures. We propose an efficient numeric scheme f...
