Universality of vortex avalanches in a type II superconductor with periodic pinning
In this work the robustness of a simple cellular automaton developed by Bassler and Paczuski (Phys. Rev. Lett. 81 (1998) 3761) to describe the critical state in type-II superconductors is studied. Two different configurations of pinning centers are introduced and a new universality class is found. The numerical values of the critical exponents were calculated following two scaling techniques to ensure the validity of our results.
