We study the critical behavior of the d=3 Ising model with bond randomness through extensive Monte Carlo simulations and finite-size scaling techniques. Our results indicate that the critical behavior of the random-bond model is governed by the same universality class as the site- and bond-diluted models, clearly distinct from that of the pure model, thus providing a complete set of universality in disordered systems.

Wang-Landau study of the 3D Ising model with bond disorder
Abstract We implement a two-stage approach of the Wang-Landau algorithm to investigate the critical properties of the 3D Ising model with quenched bond randomness. In particular, we consider the caseExpand
Universality aspects of the d = 3 random-bond Blume-Capel model.
Evidence that the second-order transition emerging under bond randomness from the first-order regime of the pure model belongs to a new and distinctive universality class is found, reinforcing the scenario of a single universalityclass for the 3d Ising model with the three well-known types of quenched uncorrelated disorder.

Monte Carlo study of the triangular Blume-Capel model under bond randomness.
The results verify previous renormalization-group calculations on the Blume-Capel model with disorder in the crystal-field coupling and find evidence that, the second-order transition emerging under bond randomness from the first-order regime of the pure model, belongs again to the same universality class.

Corrections to scaling in the dynamic approach to the phase transition with quenched disorder
With dynamic Monte Carlo simulations, we investigate the continuous phase transition in the three-dimensional three-state random-bond Potts model. We propose a useful technique to deal with theExpand
Nonequilibrium Relaxation Study of Effect of Randomness on Critical Universality Classes of Ferromagnetic Phase Transitions
The ferromagnetic critical exponents are estimated along the phase boundary for the gauge glass model in three dimensions. The nonequilibrium relaxation method is applied to estimate the transitionExpand
Universality aspects of the 2d random-bond Ising and 3d Blume-Capel models
AbstractWe report on large-scale Wang-Landau Monte Carlo simulations of the critical behavior of two spin models in two- (2d) and three-dimensions (3d), namely the 2d random-bond Ising model and theExpand
Crossover effects in dilute magnetic materials by finite-time dynamics method
Crossover phenomena are ubiquitous in disordered system. However, the crossover effects from the competition between different fixed points make it hard to identify the asymptotic scaling regimeExpand
Critical aspects of three-dimensional anisotropic spin-glass models
We study the three-dimensional ± J Ising model with a longitudinal anisotropic bond randomness on the simple cubic lattice. The random exchange interaction is applied only in the z direction, whereasExpand
Monte Carlo renormalization group of dilute 3D Ising dynamics
Simulation of critical relaxation of the magnetization in a three-dimensional Ising model diluted by quenched nonmagnetic impurity atoms is carried out. The cubic systems with linear size L = 144 andExpand
Fluids in porous media: the case of neutral walls.
The main finding is that, in the presence of the porous medium, a liquid-vapor critical point still exists and, at the critical point, the distribution of the order parameter remains scale invariant, but self-averaging is violated. Expand
