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 …

In this review we study quantum field theories and conformal field theories with global symmetries in the limit of large charge for some of the generators of the symmetry group. At low energy the sectors of the theory with large charge are described …

We study the ratio of pairs of adjacent correlators of Coulomb-branch operators in SU(2) N=2 SQCD with four flavors within the framework of the Large Quantum Number Expansion. Capitalizing on the order-by-order S-duality invariance of the …

We investigate the properties of near-conformal dynamics in a sector of large charge when approaching the lower boundary of the conformal window from the chirally broken phase. To elucidate our approach we use the time-honored example of the …

I will present the large-charge construction and some examples of applications to vector models and supersymmetric models

I will present the large-charge construction for CFT with isolated vacua.

Strong coupling cannot be avoided in the description of physical systems. I propose a definition based on the path integral formalism, quickly review some approaches for strongly-coupled systems and propose a notion of local strong coupling, where …

I will present the large-charge construction for CFT with isolated vacua and discuss its application to asymptotically safe theories and an effective model of walking dynamics.
