Vortex Pull by an External Current
arXiv:cond-mat/9708235 · doi:10.1103/PhysRevB.57.10790
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 in agreement to earlier analytical predictions. In the presence of dissipation the vortex undergoes skew deflection at an angle with respect to the external current. It is shown analytically and verified numerically that the angle and the speed of the vortex are linked through a simple mathematical relation.
