Asymptotics in the bi Yang Baxter Sigma Model
Working in a sector of large charge is a powerful tool to analytically access models that are either strongly coupled or otherwise …

The unitary Fermi gas at large charge and large N
We study the unitary Fermi gas in a harmonic trapping potential starting from a microscopic theory in the limit of large charge and …

Goldstone Bosons and Convexity
We study the spectrum of scalar charged operators in CFTs with a U(1) global symmetry. The charged operators are dual, by the …

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 …
