We study the propagation of neutrinos in gravitational fields using wave functions that are exact to first order in the metric deviation. For illustrative purposes, the geometrical background is represented by the Lense-Thirring metric. We derive explicit expressions for neutrino deflection, helicity transitions, flavor oscillations, and oscillation Hamiltonian. 
Neutrino flavor oscillations in a curved space-time
Using a WKB approximation of the Dirac equation in a curved spacetime, we obtain the expression for the phase shift between two neutrino mass eigenstates in a generic gravitational field. We apply
Neutrino Dynamics in a Quantum-Corrected Schwarzschild Spacetime
We study neutrino propagation in a curved spacetime background described by the Schwarzschild solution with the addition of quantum corrections evaluated in the framework of perturbative quantum
Gravitational Effects on Neutrino Decoherence in the Lense–Thirring Metric
We analyze the effects of gravity on neutrino wave packet decoherence. As a specific example, we consider the gravitational field of a spinning spherical body described by the Lense–Thirring metric.
Interference Phase of Mass Neutrino in Schwarzschild de Sitter Field
We calculate the interference phase of the mass neutrinos in high energy limit propagating in radial and nonradial directions along the geodesic by solving Hamilton-Jacobi equation, and discuss the

Spin–gravity coupling and gravity-induced quantum phases
External gravitational fields induce phase factors in the wave functions of particles. The phases are exact to first order in the background gravitational field, are manifestly covariant and gauge
The Maxwell and Maxwell–de Rham equations can be solved exactly to first order in an external gravitational field. The gravitational background induces phases in the wave functions of spin-1
Neutrino Oscillations in the Robertson-Walker Metric and the Cosmological Blue Shift of the Oscillation Length
The Doppler effect of the neutrino oscillation length in the flat space is discussed. When the observer travels away from the source, the oscillation length decreases. Moreover, the mass neutrino


Gravitational effects on the neutrino oscillation

Neutrino oscillations in the presence of strong gravitational fields are studied and it is observed that spin flavor resonant transitions of such neutrinos may occur in the vicinity of AGN due to gravitational effects and due to the presence a large magnetic field.
Gravitationally induced neutrino-oscillation phases
AbstractIn this essay, we introduce a new effect of gravitationally induced quantum mechanical phases in neutrino oscillations. These phases arise from a hitherto unexplored interplay of gravitation
Chirality transitions in gravitational fields.
The chirality transitions induced by gravitational fields on Dirac particles are studied within the framework of field theory in curved spaces, and an upper bound for the corresponding amplitude is estimated.
General Relativistic Effects of Gravity in Quantum Mechanics A Case of Ultra-Relativistic, Spin 1/2 Particles
We present a general relativistic framework for studying gravitational effects in quantum mechanical phenomena. We concentrate our attention on the case of ultra-relativistic, spin1/2 particles
Interplay of gravitation and linear superposition of different mass eigenstates
The interplay of gravitation and the quantum-mechanical principle of linear superposition induces a new set of neutrino oscillation phases. These ensure that the flavor-oscillation clocks, inherent
