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 …

Nonrelativistic CFTs at Large Charge: Casimir Energy and Logarithmic Enhancements

The unitary Fermi gas, by virtue of its description as a nonrelativistic conformal field theory, has proven an interesting system by …

Convexity, large charge and the large-N phase diagram of the φ⁴ theory

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 …

Following the flow for large N and large charge

We discuss the O(2N) vector model in three dimensions. While this model flows to the Wilson-Fisher fixed point when fine tuned, working …
