Abstract

We study the q-state Potts antiferromagnet with q=3 on the honeycomb lattice. Using an analytic argument together with a Monte Carlo simulation, we conclude that this model is disordered for all T 0. We also calculate the ground state entropy to be S0/kB = 0.507(10) and discuss this result.
