Simple Model of Superconducting Vortex Avalanches
Simple Model of Superconducting Vortex Avalanches
We introduce a simple lattice model of superconducting vortices driven by repulsive interactions through a random pinning potential. The model describes the behavior at the scale of the London length lambda or larger. It self-organizes to a critical state, characterized by a constant flux density gradient, where the activity takes …
