In this paper we show that, in chiral metals, optical gyrotropy is a consequence of Berry curvature in momentum space. We describe a physical picture showing that gyrotropy in chiral metals is closely related to the anomalous Hall effect in itinerant ferromagnets. We then calculate the magnitude of

WebNational Center for Biotechnology Information WebFeb 25, 2024 · The relative strength of the gyrotropic term with respect to the permeability term decides the number of isofrequency surfaces which can exist in a gyromagnetic medium. We show that gyrotropy can either suppress an isofrequency surface or support an otherwise nonexistent isofrequency surface.
WebAbstract. We study theoretically and experimentally a new mechanism for the rotation of the polarization ellipse of a single laser beam propagating through an atomic vapor with a frequency tuned near an atomic resonance. The results of a theoretical treatment for the case of a J = 1/2 to J = 1/2 atomic transition show that a rotation of the ...
