Large Charge at large N (Lyon)
The large charge approach allows to describe special sectors of strongly-coupled systems. When another controlling parameter is present, it is still useful because it allows to unveil interesting mathematical structures and access previously unexplored parts of the spectrum

N=2 SUSY at large R-charge (Paris)
I will discuss the behavior of N=2 supersymmetric theories in the large R-charge limit. Writing an effective action on moduli space, we …

Spinning correlators in large-charge CFTs
We systematically study correlators of a generic conformal field theory with a global O(2) symmetry in a sector of large global charge.

2D CFTs - Large Charge is not enough
In this note we study two-dimensional CFTs at large global charge. Since the large-charge sector decouples from the dynamics, it does …
