Nonequilibrium depinning transition of ac driven vortices with random pinning

open access: yesNew Journal of Physics, 2017
We study the critical behavior associated with transient dynamics of vortices near the depinning transition by an ac drive. From ${I}_{{\rm{ac}},{\rm{e}}}$ – ${V}_{{\rm{ac}},{\rm{e}}}$ curves at different frequencies f , where ${I}_{{\rm{ac}},{\rm{e ...
