考虑质量效应的混合态中的vortex物质的Brownian运动

摘要

Use MCFM and Krameres escape rate method, we investigate the creep behavior of pinned vortices in mixed state with inertial effect been taken into account. We find that the dynamic behavior is similar to that of the overdamped case. We reproduce the current-Voltage characteristic without using venous glass model or any special function dependence of pinning potential on the external current. The effective height of creep potential is decreasing nonlinearly with increasing external current and the escape rate of vortex from pinning wen is decreasing when the mass of vortex is increasing.
