Abstract

We study the conditions for spontaneous symmetry breaking of the 2+1 dimensional noncommutative φ6-model in the small-θ limit. In this regime, considering the model as a cutoff theory, it is reasonable to assume translational invariance as property of the vacuum state, and study the conditions for spontaneous symmetry breaking by an effective potential… (More)
