I will discuss the IR fixed point of the O(N) vector model in 3 dimensions (Wilson-Fisher point) in the framework of the large charge expansion. First I will construct an EFT valid for any N, then verify the prediction of the model in the double …

In this note we discuss the phase space of the O(2N) vector model in the presence of a quadratic and a quartic interaction by writing the large-N effective potential using large charge methods in dimensions 2

We discuss the O(2N) vector model in three dimensions. While this model flows to the Wilson-Fisher fixed point when fine tuned, working in a double-scaling limit of large N and large charge allows us to study the model away from the critical point …

Working in sectors of large global charge leads to important simplifications when studying strongly coupled CFTs. After an introduction to the method I will show how the large-charge expansion can be used to compute the large-N effective potential …

Working in sectors of large global charge leads to important simplifications when studying strongly coupled CFTs. In this talk I will introduce the large-charge expansion via the simple example of the O(2) model and apply it in a number of other …

We consider large-R-charge Coulomb branch correlation functions in N=2 superconformal QCD in D=4 dimensions, with gauge group SU(2) and $N_f = 4$ hypermultiplets in the fundamental representation. Using information from supersymmetric recursion …

We study the O(2N) model at criticality in three dimensions in the double scaling limit of large N and large charge. We show that the large-charge expansion is an asymptotic series, and we use resurgence techniques to study the non-perturbative …
