Abstract

In this work, we investigate the influence of quantum gravity induced corrections on the entanglement entropy associated with two flavor neutrino oscillations in vacuum. Using the Von Neumann entropy as a measure of quantum correlations, we analyze how Planck scale suppressed modification implemented through quantum gravity motivated changes in the neutrino dispersion relation affect the evolution of entanglement during successive oscillation cycles. By performing a statistical study over a range of oscillation lengths and neutrino energies, we identify characteristic deviations in the entropy profile arising from quantum gravity effects. Our results suggest that entanglement entropy provides a sensitive probe of small quantum gravity induced departures from standard neutrino oscillation dynamics, highlighting its potential role in testing Planck scale physics within neutrino phenomenology.
