• Abstract: We investigate neutrino decoherence within the framework of quantum spacetime, focusing on the $\kappa$-Minkowski model. We show that stochastic fluctuations in quantum spacetime induce an energy-dependent decoherence effect, where the decoherence rate scales as $E^{-4}$. This result aligns with recent IceCube observations, indicating that quantum gravity does not induce significant decoherence for high-energy neutrinos. Additionally, we establish conditions under which quantum spacetime effects could influence relic neutrinos, such as those in the cosmic neutrino background ($C\nu B$). Our results shed light on how quantum spacetime fluctuations impact neutrino oscillation physics.

We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
