Two Flavour Neutrino Oscillation in Matter and Quantum Entanglement

In this article, we investigate the entanglement entropy for neutrino oscillations when neutrino propogate in matter, utilising Von Neumann entropy. We discuss two flavour neutrino oscillation in vaccum and matter. We demonstrate statistically that, depending on the length of oscillation for each energy, the entanglement entropy for the succeeding periods of the two-flavor neutrino oscillations in matter.
