SUPERCURRENT FORCE ON AND QUASI-PARTICLES STATES IN A MOVING VORTEX LINE

The exchange of Cooper pair momentum between the normal core electrons and the superconducting condensate around a moving vortex line in a h igh-kappa superconductor is computed with the help of the recently dis covered supercurrent force on Andreev scattered quasiparticles. This r esults in half of the Magnus force and explains microscopically the ph enomenologically introduced interface force of the Nozieres-Vinen-Warr en theory which is missing in the Bardeen-Stephen theory. Solutions of the time dependent Bogoliubov-de Gennes equations (BdGE) for a moving vortex line without the high-kappa restriction are discussed.
