Monte Carlo study of a compressible Ising antiferromagnet on a triangular lattice.
We have studied the compressible antiferromagnetic Ising Model on a triangular lattice using Monte Carlo simulations. It is found that the coupling to the strain removes the frustration of the rigid model and the simulations show a transition from the disordered to an ordered, striped phase at low temperatures. This transition involves two broken symmetries: the Ising symmetry and a three-state...
متن کاملMonte Carlo Simulation of the Three-dimensional Ising Spin Glass
Abstract. We study the 3D Edwards–Anderson model with binary interactions by Monte Carlo simulations. Direct evidence of finite–size scaling is provided, and the universal finite–size scaling functions are determined. Using an iterative extrapolation procedure, Monte Carlo data are extrapolated to infinite volume up to correlation length ξ ≈ 140. The infinite volume data are consistent with bot...
متن کاملMonte Carlo Simulation of a Random-Field Ising Antiferromagnet
Phase transitions in the three-dimensional diluted Ising antiferromagnet in an applied magnetic field are analyzed numerically. It is found that random magnetic field in a system with spin concentration below a certain threshold induces a crossover from second-order phase transition to first-order transition to a new phase characterized by a spin-glass ground state and metastable energy states ...
متن کاملCritical Behavior of the Ferromagnetic Ising Model on a Sierpiński Carpet: Monte Carlo Renormalization Group Study
We perform a Monte Carlo Renormalization Group analysis of the critical behavior of the ferromagnetic Ising model on a Sierpiński fractal with Hausdorff dimension df ≃ 1.8928. This method is shown to be relevant to the calculation of the critical temperature Tc and the magnetic eigen-exponent yh on such structures. On the other hand, scaling corrections hinder the calculation of the temperature...
متن کاملThree-dimensional randomly dilute Ising model: Monte Carlo results.
We perform a high-statistics simulation of the three-dimensional randomly dilute Ising model on cubic lattices L3 with L< or =256. We choose a particular value of the density, x=0.8, for which the leading scaling corrections are suppressed. We determine the critical exponents, obtaining nu=0.683(3), eta=0.035(2), beta=0.3535(17), and alpha=-0.049(9), in agreement with previous numerical simulat...
