| Abstract (English): |
One of the most thrilling features of Physics is the possibility of establishing analogies between apparently distant areas. Here, we explain the parallel between a pile of grains interacting mechanically with each other, and a "pile" of superconducting vortices. In both cases the macroscopic slope of the pile is maintained by a very nonlinear avalanche process. Furthermore, both types of piles logarithmically relax in time due to "agitational" or thermal effects, aiming at a state of equilibrium. [ABSTRACT FROM AUTHOR] |

Uno de los aspectos más apasionantes de la Física es la posibilidad de establecer analogías entre áreas aparentemente distantes entre sí. Aquí explicamos el paralelo entre una pila de granos que interactúan mecánicamente entre sí, y una "pila" de vórtices superconductores. En ambos casos la pendiente de la pila se mantiene mediante avalanchas altamente no lineales. Además, ambos tipos de pilas se relajan en el tiempo debido a efectos "agitativos" o térmicos, apuntando hacia un estado de equilibrio. [ABSTRACT FROM AUTHOR] |
