Functional renormalization group perspective on the Berezinskii-Kosterlitz-Thouless transition
I will review the functional renormalization group approach to the classical O(N) models in two and three spatial dimensions. I will discuss in some detail the specific case of N=2 and d=2, corresponding to the Berezinskii-Kosterlitz-Thouless universality class.
