Abstract
The Fermi liquid has an emergent low-energy symmetry that corresponds to charge conservation at each momentum on the Ferm surface. Recently Else, Thorngren and Senthil (ETS) argued that the emergent symmetry had a specific t'Hooft anomaly. We give a simple derivation of the ETS anomaly using the chiral anomaly of Weyl fermions.
