Optical gyrotropy
WebNov 27, 2014 · The optical activity of oriented molecular systems is investigated using bianisotropic material constitutives for Maxwellʼs equations. It is shown that the circular birefringence and circular dichroism for an oriented system can be conveniently expressed in terms of the two components of the symmetric magnetoelectric tensor of gyrotropy … WebFeb 5, 2010 · ABSTRACT Functional photonic crystals fabricated in iron garnet films are shown to provide magnetically-controllable optical switching. Transverse-electric and transverse-magnetic stop band separation in conjunction with optical gyrotropy are utilized to selectively block and transmit near-infrared light in waveguide geometries.

WebMar 9, 2015 · Optical gyrotropy from axion electrodynamics in momentum space Shudan Zhong, Joseph Orenstein, Joel E. Moore Several emergent phenomena and phases in solids arise from configurations of the electronic Berry phase in momentum space that are similar to gauge field configurations in real space such as magnetic monopoles. Webchirality generates gyrotropy. 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
