Abstract

We study the low-temperature properties of the classical three-dimensional compass or t(2g) orbital model on simple-cubic lattices by means of comprehensive large-scale Monte Carlo simulations. Our numerical results give evidence for a directionally ordered phase that is reached via a first-order transition at the temperature T-0 = 0.098 328(3) J/k(B). To obtain our results, we employ local and cluster update algorithms, parallel tempering and multiple histogram reweighting as well as model-specific screw-periodic boundary conditions, which help counteract severe finite-size effects.
