Abstract
The electromagnetic response of a pinned Abrikosov fluxoid is examined in the framework of the Bogoliubov–de Gennes formalism. The matrix elements and the section rules for both the single photon (emission-absorption) and two photon (Raman scattering) processes are obtained. The results reveal striking asymmetries: light absorption by quasiparticle pair creation or single quasiparticle scattering can occur only if the handedness of the incident radiation is opposite to that of the vortex core states. We show how these effects will lead to nonreciprocal circular birefringence, and also predict structure in the frequency dependence of conductivity and in the differential cross section of the Raman scattering.
