Description
We study three neutrino mixing and oscillations and find the pattern of oscillations in nuclear media and strong magnetic fields using effective Hamiltonian. We observe that for high energy neutrinos, neutrino oscillations are suppressed in the presence of nuclear media. We compare our results with neutrino oscillation in vacuum and also with other works done for two flavour neutrino mixing.
On the other hand, Lorentz invariance is a well known fundamental predictions of special relativity but its violation is predicted by some variations of quantum gravity, string theory, and some alternatives to general relativity. We also study neutrino oscillation at the presence of the Lorentz invariance violation in nuclear media. Many attempts have been made to measure Lorentz violations. Our results indicate that, neutrino mixing of high energy cosmic neutrinos can help us to probe neutron stars, pulsars, supernovas and also to check Lorentz invariance violation.
