Vortex dynamics in twinned superconductors

Vortex Plastic Motion in Twinned Superconductors.

We present simulations, without electrodynamical assumptions, of Bsx, y, Hstdd, MsHstdd, and JcsHstdd in hard superconductors for a variety of twin-boundary pinning potential parameters, and for a range of values of the density and strength of the pinning sites. We numerically solve the overdamped equations of motion of up to 10 flux-gradient-driven vortices which can be temporarily trapped at ...

Vortex dynamics for low- type-II superconductors

Vortex Fluctuations in Superconductors

The vortex fluctuations have proved to be responsible for the onset of dissipation in thin type-II superconducting Aims. There is also growing evidence that dissipation in hightemperature superconductors exhibits the same kind of two-dimensional (2D) behavior. However, a proper analysis of these materials requires a thorough understanding of the two-dimensional fluctuations. This thesis may be ...

Charge Dynamics of Vortex Cores in Layered Chiral Triplet Superconductors

In an accompanying paper [J.A. Sauls and M. Eschrig, Vortices in chiral, spin-triplet superconductors and superfluids, this issue] we have studied the equilibrium properties of vortices in a chiral quasi-twodimensional triplet superfluid/superconductor. Here we extend our studies to include the dynamical response of a vortex core in a chiral triplet superconductor to an external a.c. electromag...
