Abstract

The Bose condensate model is used to elucidate the interaction of vortex lines with impurities. Three-dimensional numerical integration of the coupled nonlinear Schrödinger equations, which describe the evolution of the wave functions of the Bose condensate and an impurity, are used to study the process of capture of the impurity by a rectilinear vortex and to elucidate the binding energy. Kelvin waves are generated during capture.
