Weyl metal: A topological Fermi-liquid state beyond Landau Fermi liquids
Weyl metal is a topological Fermi-liquid state with a pair of chiral Fermi surfaces, which encode
not only Berry curvature but also chiral anomaly. As a result, descriptions based on conventional
Maxwell equations fail to detect their electromagnetic properties. Instead, their characteristic
features are described by axion electrodynamics, given by the topological-in-origin E·B term.
Then, it is natural to investigate how well-known physical properties of non-topological Landau
Fermi liquids will be modified by the axion electrodynamics of a pair of chiral Fermi surfaces.
In this colloquium we address how fundamental properties of non-chiral Fermi surfaces are changed
in the case of chiral Fermi surfaces.
