Title: Nonperturbative RG flow and IR effective action of the O(N) vector model
Abstract: In this talk, I will discuss our study on the exact RG flow of the O(N) vector model using nonperturbative quantum RG approach. We show that the beta functions in the entire coupling space are highly constraint and can be expressed in terms of beta functions defined in the subspace of couplings. Then, following the RG flow, I will present how to get the IR effective action of this O(N) model.
