AbstraktAbstract
Light passing through the medium of massive neutral Dirac fermions with magnetic moment might experience change in the index of refraction with respect to vacuum. Possible candidates for a pure medium of massive neutral dirac fermions with magnetic moment are cosmic neutrino background (CNB) and dark matter (DM). In this work, using thermal quantum field theory and its real-time formalism, we calculate the correction to the photon index of refraction due to the presence of medium of neutral Dirac fermions with CNB-like statistical properties, for which we find exactly zero effect.
