Non-Fermi Liquids as Ersatz Fermi Liquids: General Constraints on Compressible Metals
A system with charge conservation and lattice translation symmetry has a well-defined filling ν, which is a real number representing the average charge per unit cell. We show that if ν is fractional (i.e., not an integer), this imposes very strong constraints on the low-energy theory of the system a...
