We introduce a new axial-next-nearest-neighbor model that can be solved analytically. The model shows spatially modulated phases in Monte Carlo calculations. As only one critical temperature is found and in agreement with transfer-matrix results the modulated phases are found to be metastable. According to the results of this model we expect nonequilibrium effects in experiments with longer ...
