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 which velocity of the vortex depends upon the local curvature and orientation. A system of closely packed vortices is then considered, and a mean field model is formulated in which the individual vortex lines are replaced by a vortex density

Study of Anisotropy Superconductor using Time-Dependent Ginzburg-Landau Equation

We have observed an anisotropy superconductor which was immersed in vacuum medium in presence of an applied magnetic field. The anisotropy properties of superconductor were related with two principal values of the effective mass of the Cooper pairs, namely mc along the x-axis and mab in the yz-plane. Based on the time-dependent Ginzburg-Landau and yU methods, the problem was solved and made to be the numerical simulation. From study using this numerical simulation, we can find that the anisotropy properties can make the critical field to be lower or higher.
