Model for the propagation of fermions in a Bose-Einstein condensate

José F. Nieves, Sarira Sahu

We consider the dispersion relations of fermions that propagate in the background of a scalar Bose-Einstein condensate. Some illustrative examples are discussed using simple Yukawa…

Neutrino effective potential and damping in a fermion and scalar background in the resonance region

Jose F. Nieves, Sarira Sahu

We consider the propagation of a neutrino or an antineutrino in a medium composed of fermions and scalars interacting via a Yukawa-type coupling of the form , for…

Taming the pinch singularities in the two-loop neutrino self-energy in a medium

José F. Nieves, Sarira Sahu

We consider the calculation of the thermal self-energy of a neutrino that propagates in a medium composed of fermions and scalars interacting via a Yukawa-type coupling, in the cas…

Simplified calculations of plasma oscillations with non-extensive statistics

José F. Nieves, John D. Verges

We use the exponential parametrization of the nonextensive distribution to calculate the dielectric constant in an electron gas obeying the nonextensive statistics. As we show, the…

Neutrino decoherence in an electron and nucleon background

José F. Nieves, Sarira Sahu

We consider the decoherence effects in the propagation of active neutrinos due to the non-forward neutrino scattering processes in a matter background composed of electrons and nuc…

Neutrino decoherence in a fermion and scalar background

Jose F. Nieves, Sarira Sahu

We consider the decoherence effects in the propagation of neutrinos in a background composed of a scalar particle and a fermion due to the non-forward neutrino scattering processes…
