A Theory of Neutrino Oscillations and Late Time Acceleration

TL;DR

This paper proposes a microphysical model linking neutrino oscillations to dark energy, suggesting neutrino condensates cause late-time cosmic acceleration and predict CPT violation and evolving dark energy properties.

Contribution

It introduces a novel model connecting neutrino oscillations with dark energy via a neutrino condensate, predicting CPT violation and testable cosmological effects.

Findings

Neutrino oscillations are proportional to dark energy density.

The model predicts CPT violation in neutrino oscillations.

Dark energy evolution is connected to neutrino oscillation behavior.

Abstract

We provide a microphysical model that connects neutrino oscillations to dark energy, which has predictions of Lorentz and CPT violating neutrino oscillations. We argue that the DE is a BCS condensate of flavored neutrinos. As neutrinos propigate in their own condensate they naturally have oscillations proportional to the DE energy density. All that is assumed in this model is a covariant coupling of neutrinos to gravity and a finite number density of neutrinos in the cosmic rest frame; this situation yields an attractive channel for the formation of a spin zero neutrino condensate leading to late time acceleration self consistently. Moreover, the vacuum oscillation has two predictions: (1) CPT violating oscillations proportional to the DE density (2) A connection between the evolution of the equation of state of the DE condensate and the neutrino oscillations. These predictions can be probed independently with future Supernovae and Neutrino Telescopes.
