Depinning and dynamics of ac driven vortex lattices in random media
We study the different dynamical regimes of a vortex lattice driven by ac forces in the presence of random pinning via numerical simulations. The behavior of the different observables is characterized as a function of the applied force amplitude for different frequencies. We discuss the inconvenienc...

We study the different dynamical regimes of a vortex lattice driven by ac forces in the presence of random pinning via numerical simulations.
