Photon propagation in a charged Bose-Einstein condensate

José F. Nieves, Sarira Sahu

We consider the propagation of photons in a model of a charged scalar Bose-Einstein (BE) condensate. We determine the dispersion relations of the collective modes, as well as the p…

Kinetic theory formulation of the $P$ - and $C P$ -odd terms in the photon self-energy in a medium

José F. Nieves, John D. Verges

In an optically active medium, such as a plasma that contains a neutrino background, the left-handed and right-handed polarization photon modes acquire different dispersion relatio…
