General Relativity (GR) is mainly based upon two fundamental postulates: general covariance and equivalence principle. These important topics have always represented a guiding light for the development of the most successful gravitational theory we have at disposal.

Recently, it has been pointed out that neutrino physics in conjunction with the above principles may potentially lead to significant implementations in the context of gravitation and quantum field theory in curved spacetime. In particular, by relying on general covariance fulfillment and on a thorough investigation of the decay of an accelerated proton, one can unambiguously achieve a theoretical check for the existence of the Unruh effect. On the other hand, the possibility of analyzing neutrino oscillations in curved backgrounds entails a series of intriguing implications associated with the equivalence principle. Specifically, by analyzing neutrino propagation on a spacetime described by extended theories of gravity, one can prove that the correction to the GR contribution is intimately related to the strong equivalence principle violation. However, even in the domain of GR itself, the violation of the equivalence principle in its weak formulation for non-relativistic neutrinos is a feasible scenario.
