Vortex Pull by an External Current
Abstract
In the context of a dynamical Ginzburg-Landau model it is shown numerically that under the influence of a homogeneous external current J the vortex drifts against the current with velocity V= -J in agreement to earlier analytical predictions. In the presence of dissipation the vortex undergoes skew deflection at an angle 90 < δ < 180 with respect to the external current. It is shown analytically and verified numerically that the angle δ and the speed of the vortex are linked through a simple mathematical relation.
