Tests of General Relativity at the Quantum Level

We consider several tests of general relativity at the quantum level. One of these is based on the observation that an effect of a gravitational field on a hydrogen atom is to admix states of opposite parity such as 2S1/2 and 2P1/2. This leads to a circular polarization Pγ of emitted radiation which could be sufficiently large to be detected in white dwarfs or in certain binary systems. Since the magnitude of Pγ varies from theory to theory, it is possible that a study of this effect could provide a feasible means of testing general relativity at the quantum level. We also discuss the phenomenon of gravity-induced CP-violation in fermion-antifermion systems and possible applications to KL decays.
