Phase transitions in the Potts spin-glass model
نویسندگان
چکیده
We have studied the Potts spin glass with two-state Ising spins and s-state Potts variables using a cluster Monte Carlo dynamics. The model recovers the 6J Ising spin glass ~SG! for s51 and exhibits for all s a SG transition at TSG(s) and a percolation transition at higher temperature Tp(s). We have shown that for all values of sÞ1 at Tp(s) there is a thermodynamic transition in the universality class of a ferromagnetic s-state Potts model. The efficiency of the cluster dynamics is compared with that of standard spin-flip dynamics. @S1063-651X~98!03708-8#

Magnetic Properties and Phase Transitions in a Spin-1 Random Transverse Ising Model on Simple Cubic Lattice
Within the effective-field theory with correlations (EFT), a transverse random field spin-1 Ising model on the simple cubic (z=6) lattice is studied. The phase diagrams, the behavior of critical points, transverse magnetization, internal energy, magnetic specific heat are obtained numerically and discussed for different values of p the concentration of the random transverse field.
متن کاملPrecursor phenomena in frustrated systems.
To understand the origin of the dynamical transition, between high-temperature exponential relaxation and low-temperature nonexponential relaxation, that occurs well above the static transition in glassy systems, a frustrated spin model, with and without disorder, is considered. The model has two phase transitions, the lower being a standard spin glass transition (in the presence of disorder) o...
متن کاملThe Cavity Approach for Metastable Glassy States Near Random First Order Phase Transitions
Ii is shown that trie cavity method developed to describe equilibrium states in trie mean-field Ising spin glass model con be generalized to describe metastable stores in trie mean-field Potts glass. Trie crucial input is trie existence of an extensive number of statistically similar but incongruent metastable states with a weighted Gaussian free energy distribution. It is argued that the inher...
متن کاملChiral Potts spin glass in d=2 and 3 dimensions.
The chiral spin-glass Potts system with q=3 states is studied in d=2 and 3 spatial dimensions by renormalization-group theory and the global phase diagrams are calculated in temperature, chirality concentration p, and chirality-breaking concentration c, with determination of phase chaos and phase-boundary chaos. In d=3, the system has ferromagnetic, left-chiral, right-chiral, chiral spin-glass,...
متن کاملCorrelated Percolation and the Phase Transitions in Ising-like Spin Models*
Considering each lattice site with a spin occupied and the lattice site without a spin unoccupied, we could formally show that the partition functions of many Ising-like spin models are the generating functions of correlated percolation models. Each correlated percolation model has the same critical properties as the corresponding spin model. From such connections, we could physically understan...
