Monte Carlo Study of an Extended 3-State Potts Model on the Triangular Lattice

摘要

By introducing a chiral term into the Hamiltonian of the 3-state Potts modelon a triangular lattice additional symmetries are achieved between theclockwise and anticlockwise states and the ferromagnetic state. This model isinvestigated using Monte Carlo methods. We investigate the full phase diagramand find evidence for a line tricritical points separating the ferromagneticand antiferromagnetic phases.
