| Summary:
We study the large-charge sector of large-N fermionic CFTs in three
dimensions. Depending on the model and the nature of the fixed charge, we find
two types of descriptions: in terms of a superfluid or a Fermi sphere. We
explicitly compute the conformal dimensions of the lowest operator of fixed
charge and in the superfluid case verify the EFT predictions for the phonon
spectrum.
