Numerical approach to metastable states in the zerotemperature randomfield Ising model
PerezReche, Francisco J.; Rosinberg, Martin L.; Tarjus, Gilles (American Physical Society, 200802)We study numerically the number of singlespinflip stable states in the T=0 random field Ising model on random regular graphs of connectivity z=2 and z=4 and on the cubic lattice. The annealed and quenched complexities ... 
Stable, metastable and unstable states in the meanfield randomfield Ising model at T = 0
Rosinberg, Martin L.; Tarjus, Gilles; PerezReche, Francisco J. (Institute of Physics, 200810)We compute the probability distribution of the number of metastable states at a given applied field in the meanfield randomfield Ising model at T = 0. Remarkably, there is a nonzero probability in the thermodynamic limit ... 
The T = 0 randomfield Ising model on a Bethe lattice with large coordination number: hysteresis and metastable states
Rosinberg, Martin L.; Tarjus, Gilles; PerezReche, Francisco J. (Institute of Physics, 200903)In order to elucidate the relationship between rateindependent hysteresis and metastability in disordered systems driven by an external field, we study the Gaussian RFIM at T = 0 on regular random graphs (Bethe lattice) ...
