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 …
