Abstract
Using a simple cellular automata with stochastic rules, we show the possible emergence of thermally activated avalanches (power law distributed) in type-II superconductors. Scaling relations between the exponents characterizing these distributions and those obtained from field-driven experiments are derived and proved through simulations. It is also shown that the conditions for the appearance of these avalanches are independent of the pinning mechanism. The relevance of our simulations for recently reported experimental results is also outlined.
