The gravitational neutrino oscillation problem is studied by considering the Dirac Hamiltonian in a Riemann-Cartan space-time and calculating the dynamical phase. Torsion contributions which depend on the spin direction of the mass eigenstates are found. These effects are of the order of Planck scales.

Spin-dependent neutrino oscillations in torsion backgrounds: A quantum-field-theoretic analysis
Constant spatial torsion induces spin-dependent effective masses for neutrinos that modify both frequencies and amplitudes of flavor oscillations in the QFT description, with largest effects at low momentum when torsi...
