Studying avalanches in the ground state of the two-dimensional random-field ising model driven by an external field
We study the exact ground state of the two-dimensional random-field Ising model as a function of both the external applied field B and the standard deviation sigma of the Gaussian random-field distribution. The equilibrium evolution of the magnetization consists in a sequence of discrete jumps. Thes...
