Critical Behavior of the Three-Dimensional Ising Spin Glass
H. G. Ballesteros, A. Cruz, L. A. Fernandez +7
We have simulated, using parallel tempering, the three dimensional Ising spin glass model with binary couplings in a helicoidal geometry. The largest lattice (L=20) has been studie…
Effect of Dilution on First Order Transitions: The Three Dimensional Three States Potts Model
H. G. Ballesteros, L. A. Fernandez, V. Martin-Mayor +3
We have studied numerically the effect of quenched site dilution on a first order phase transition in three dimensions. We have simulated the site diluted three states Potts model…
Site-diluted three dimensional Ising Model with long-range correlated disorder
H. G. Ballesteros, G. Parisi
We study two different versions of the site-diluted Ising model in three dimensions with long-range spatially correlated disorder by Monte Carlo means. We use finite-size scaling t…
A new test for random number generators: Schwinger-Dyson equations for the Ising model
H. G. Ballesteros, V. Martin-Mayor
We use a set of Schwinger-Dyson equations for the Ising Model to check several random number generators. For the model in two and three dimensions, it is shown that the equations a…
Finite Size Scaling and ``perfect'' actions: the three dimensional Ising model
H. G. Ballesteros, L. A. Fernandez, V. Martin-Mayor +1
Using Finite-Size Scaling techniques, we numerically show that the first irrelevant operator of the lattice theory in three dimensions is (within errors) completely decouple…
Critical exponents of the three dimensional diluted Ising model
H. G. Ballesteros, L. A. Fernandez, V. Martin-Mayor +3
We study the phase diagram of the site-diluted Ising model in a wide dilution range, through Monte Carlo simulations and Finite-Size Scaling techniques. Our results for the critica…
