摘要：

The propagation of dislocations in random crystals is evidenced to be governed by atomic-scale avalanches whose extension in space and time intermittency characterizingly diverge at the critical threshold. Our work is evidence that the paradigm of second-order phase transitions applies to the depinning of elastic interfaces in random media down to atomic-scale.
