Abstract

The mock ANNNI model is generalized in replacing the Ising spins by q-state Potts variables. Performing exact dedecoration transformations for general q and using Monte Carlo techniques in two dimensions for q=3, a multitude of distinct spatially modulated long-range ordered phases, as well as phases with algebraic order, are found to spring from multiphase point.
