Abstract
Using a simple cellular automata with stochastic rules, we show the possibl e emergence of thermally activated avalanches (power law distributed) in ty pe-II superconductors. Scaling relations between the exponents characterizi ng these distributions and those obtained from field-driven experiments are derived and proved through simulations. It is also shown that the conditio ns for the appearance of these avalanches are independent of the pinning me chanism. The relevance of our simulations for recently reported experimenta l results is also outlined.
