Exact calculation of the energy contributions to the T=0 random-field Ising model with metastable dynamics on the Bethe lattice
Xavier Illa, Jordi Ortin, Eduard Vives
We analyze the energy terms corresponding to the spin-spin exchange and spin-random field coupling of the zero temperature random-field Ising model on the Bethe lattice driven by a…
Hysteresis and avalanches in the T=0 random-field Ising model with 2-spin-flip dynamics
Eduard Vives, Martin Luc Rosinberg, Gilles Tarjus
We study the non-equilibrium behavior of the three-dimensional Gaussian random-field Ising model at T=0 in the presence of a uniform external field using a 2-spin-flip dynamics. Th…
Driving rate effects in avalanche-mediated, first-order phase transitions
Francisco-Jose Perez-Reche, Bosiljka Tadic, Lluis Manosa +2
We have studied the driving rate and temperature dependence of the power-law exponents that characterize the avalanche distribution in first-order phase transitions. Measurements o…
Spanning avalanches in the three-dimensional Gaussian Random Field Ising Model with metastable dynamics: field dependence and geometrical properties
Francisco-Jose Perez-Reche, Eduard Vives
Spanning avalanches in the 3D Gaussian Random Field Ising Model (3D-GRFIM) with metastable dynamics at T=0 have been studied. Statistical analysis of the field values for which ava…
Long range Ising model for credit risk modeling in homogeneous portfolios
Jordi Molins, Eduard Vives
Within the framework of maximum entropy principle we show that the finite-size long-range Ising model is the adequate model for the description of homogeneous credit portfolios and…
