Vorticity and magnetic shielding in a type-II superconductor.
We study in detail, solving the Bogoliubov-de Gennes equations, the magnetic field, supercurrent and order parameter profiles originated by a solenoid or magnetic whisker inserted in a type-II superconductor. We consider solutions of different vorticities, n, in the various cases. The results confirm the connection between the vorticity, the internal currents and the boundstates in a self-consi...

On the Magnetic-Field Dependence of the Longitudinal Ultrasonic Attenuation in a Type-II Superconductor
We propose a simple method by which we can explain the magnetic-field dependence of the longitudinal ultrasonic attenuation in a type-II superconductor. It gives a curve which is in good agreement with experimental data, in paticular, near the lower critical field Hc1. We compare it with conventional methods, which is not in good agreement with the experimental data near Hc1 but near the upper ...
متن کاملVisualization of the Vortex Dynamics in a Type-II Superconductor in a Periodic Dissipative State
Using state-of-the-art analytic techniques for extracting a singularity from a complex field, we can visualize the vortices in the largest time-dependent Ginsburg Landau simulation of a superconductor performed to date. Our visualization reveals the internal dynamics of the vortices in the superconductor, explaining the cause of a voltage spike in the electro-magnetic response of the system. Th...
متن کاملEdge and Bulk Transport in the Mixed State of a Type-II Superconductor
By comparing the voltage-current (V − I) curves obtained before and after cutting a sample of 2HNbSe2, we separate the bulk and edge contributions to the transport current at various dissipation levels and derive their respective V − I curves and critical currents. We find that the edge contribution is thermally activated across a current dependent surface barrier. By contrast the bulk V − I cu...
