TL;DR

This paper explores how a periodic matter structure can enhance the conversion of cosmic background neutrinos between mass states through coherent scattering, potentially releasing energy and transferring momentum.

Contribution

It introduces a novel method using periodic structures to amplify neutrino mass state conversion and energy transfer from cosmic background neutrinos.

Findings

Periodic structures can enhance neutrino mass state conversion.

Energy can be released during the scattering process.

Momentum transfer to electrons is achievable.

Abstract

We study coherent interaction of cosmic background neutrinos(CBNs) with matter of periodic structure. The mixing and small masses of neutrinos discovered in neutrino oscillation experiments indicate that CBNs which have very low energy today should be in mass states and can transform from one mass state to another in interaction with electrons in matter. We show that in a coherent scattering process a periodic matter structure designed to match the scale of the mass square difference of neutrinos can enhance the conversion of CBNs from one mass state to another. Energy of CBNs can be released in this scattering process and momentum transfer from CBNs to electrons in target matter can be obtained.
