- Title
FROM PILES OF GRAINS TO PILES OF VORTICES.

- Abstract
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.
