Title: Anomalous quantum transport - Hall, Kerr and Josephson effects
Abstract: I will review mechanisms of the anomalous Hall effect using the model of massive Dirac fermions as a guiding example. Extensions of the theory to the case of chiral p-wave superconductors will be presented in the context of the Kerr effect. We will also discuss how multi-terminal Josephson junctions can realize quantized anomalous Hall like responses which are governed by the Berry fluxes of the band topology harbored by Andreev states. The latter realize Weyl-like semi-metallic phases.
