Effect of normal current corrections on the vortex dynamics in type-II superconductors

Abstract: Within the time-dependent Ginzburg-Landau theory we discuss the effect of nonmagnetic interactions between the normal current and supercurrent in the presence of electric and magnetic fields. The correction due to the current-current interactions is shown to have a transient character so that it contributes only when a system evolves. Numerical studies for thin current-carrying superconducting strips with no magnetic feedback show that the effect of the normal current corrections is more pronounced in the resi… Show more

“…The dynamics of magnetic vortices in type II superconductors at temperatures close to the critical temperature can be modelled by the time dependent Ginzburg-Landau equations. The theory is based on a Schrödinger type equation with a potential containing a quadratic term and a quartic term in addition to a kinetic term involving the momentum operator coupled to a magnetic field governed by the Maxwell equations [1], [2], [3]. For type-II superconductors the Ginzburg-Landau equations model the magnetic field penetration through quantized current vortices as the externally applied magnetic field exceeds a threshold value.…”
