Renormalization of the Nonlinear O(3) Model with Theta-Term

Raphael Flore

The renormalization of the topological term in the two-dimensional nonlinear O(3) model is studied by means of the Functional Renormalization Group. By considering the topological…

Functional renormalization group of the non-linear sigma model and the O(N) universality class

Raphael Flore, Andreas Wipf, Omar Zanusso

We study the renormalization group flow of the O(N) non-linear sigma model in arbitrary dimensions. The effective action of the model is truncated to fourth order in the derivative…
