Dynamics of vortex penetration, jumpwise instabilities, and nonlinear surface resistance of type-Ⅱ superconductors in strong rf fields

摘要

We consider the nonlinear dynamics of a single vortex in a superconductor in a strong rf magnetic field B_0 sin ωt. Using the London theory, we calculate the dissipated power Q(B_0 ,ω) and the transient time scales of vortex motion. For the linear Bardeen
