We report on the observation of the rearrangement of vortices in the ns time scale following a fast magnetic field variation due to selective local heating of a high Tc superconducting film. Detailed simulations describing the measured photoinduced voltage signals along the film lead to a better understanding of vortex dynamics in fast regimes, where mean vortex velocities reach 10000 m/s
The objective of this paper is to study the formation of defects in a non equilibrium second order phase transition by means of a numerical solution of the full dynamical equations, and to compare the results with theoretical predictions to be found in the literature. We simulate an instantaneous quench to zero temperature in a type II superconductor, measuring the actual density of defects and its theoretically expected value as a function of time. We also characterize quantitatively some aspects of the out of equilibrium phase transition.
