Berry Curvature, Triangle Anomalies, and Chiral Magnetic Effect in Fermi
Liquids    [PDF]

Dam Thanh Son, Naoki Yamamoto

In a three-dimensional Fermi liquid, quasiparticles near the the Fermi surface may possess Berry curvature. We show that if the Berry curvature has a nonvanishing flux through the Fermi surface, the particle number associated with this Fermi surface has a triangle anomaly in external electromagnetic fields. We show how Landau's Fermi liquid theory should be modified to take into account the Berry curvature. We show that the "chiral magnetic effect" also emerges from the Berry curvature flux.
