Abstract
We investigate the three-state antiferromagnetic Potts model on a simple
cubic lattice with a cluster flipping Monte Carlo simulation algorithm in the
temperature region below the transition into disorder at Tc1.
We find both
the well established broken-sublattice-symmetry (BSS) phase at low temperature
and a new, rotationally symmetric phase at higher temperature, but below
Tc1.
The properties of the second phase and the transition temperature to
the BSS phase are in disagreement with recent cluster-variation and Monte
Carlo simulation results, but in agreement with simulations by Kolesik and
Suzuki.
