We also studied a system with two different square lattices arranged to resemble the geometry found in the mixed layer pnictide oxides (........, . = .) of Brock et al. Within a restricted region of phase space, this model does exhibit the orthogonal order observed in experiments.

MC Study of the ,-state Mean-Field Potts Glassults are compatible with the expected result of a quite peculiar first-order phase transition. The specific-heat maxima .. behave qualitatively in the same way as for . = 3, consistent with the prediction that there is no latent heat.

META

Computer Simulation Studies in Condensed Matter Physics: An Introductiont the Center for Simulational Physics. Both longer, invited presentations and contributed papers are included. The reader will find that a wide range of simulational studies is covered, and there is a good deal of cross-fertilization of methods between different sub-fields.

Equilibrium and Off-Equilibrium Simulations of Chiral-Glass Order in Three-Dimensional Heisenberg Spulations. Fully isotropic model is found to exhibit a finite-temperature chiral-glass transition without the conventional spin-glass order. Although chirality is an Ising-like quantity from symmetry, universality class of the chiral-glass transition appears to be different from that of the standard

Ising Spins on 3D Random Latticesto 128 000 sites. For each lattice size quenched averages are computed over 96 realizations. From a finite-size scaling analysis we obtain strong evidence that the critical exponents coincide with those on regular cubic lattices.
