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…

Supersymmetric Nonlinear O(3) Sigma Model on the Lattice
Raphael Flore, Daniel Körner, Andreas Wipf +1
A supersymmetric extension of the nonlinear O(3) sigma model in two spacetime dimensions is investigated by means of Monte Carlo simulations. We argue that it is impossible to cons…

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…
