I will discuss the topological and geometric aspects of optical and transport phenomena in metals with nontrivial band geometry, and outline the full theory of linear-in-q contribution to the non-local conductivity in a disordered metal. Physical applications of the theory include the natural optical activity of metals and the dynamic chiral magnetic effect, as well as the kinetic magnetoelectric effect/the current-induced magnetization in metallic systems. The theory is similar in spirit to the one of the anomalous Hall effect in metals, and can be used for the analysis of the typical optical and transport measurements (e.g. Faraday rotation, current-induced magnetization) in the THz frequency range.
