Title: Large Charge Sector of 3d Parity-Violating CFTs

Abstract: I will discuss 3d CFTs that become superfluids at finite density. When parity is not a symmetry, the Goldstone EFT contains a single 1-derivative term with quantized coefficient. This term forces the superfluid ground state to have vortices on the sphere, leading to a spectrum of large charge operators that is remarkably richer than in parity-invariant CFTs. I will show how these predictions are borne out in the spectrum of monopole operators of a weakly coupled Chern-Simons matter theory. Based on https://arxiv.org/abs/2102.05046 with Umang Mehta and Gabriel Cuomo.
