Query: Emergent anomaly of Fermi surfaces: a simple derivation from Weyl
  fermions   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.
