MOTION AND HOMOGENIZATION OF VORTICES IN ANISOTROPIC TYPE-II SUPERCONDUCTORS

The motion of vortices in an anisotropic superconductor is considered. For a system of well-separated vortices, each vortex is found to obey a law of motion analogous to the local induction approximation, in wh ich velocity of the vortex depends upon the local curvature and orient ation. A system of closely packed vortices is then considered, and a m ean field model is formulated in which the individual vortex lines are replaced by a vortex density.
