Fermion scattering in a Bose-Einstein condensate
César E. Echevarría, José F. Nieves, Francisco Orbe +1
In a recent work, we considered the propagation of fermions in the background of a scalar Bose-Einstein (BE) condensate. Using some illustrative Yukawa-type coupling models between…
Plasmon damping in a charged Bose-Einstein condensate model
José F. Nieves, Sarira Sahu
In this work we consider the calculation of the imaginary part of the dispersion relations of the propagating modes in a model of a charged scalar Bose-Einstein (BE) condensate, as…
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 - and -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…
