Kinetic Spin Decoherence in a Gravitational Field
arXiv:1811.06947 · doi:10.1142/S0218271819501049
Abstract
We consider a wave packet of a spin-1/2 particle in a gravitational field, the effect of which can be described in terms of a succession of local inertial frames. It is shown that integrating out of the momentum yields a spin mixed state, with the entropy dependent on the deviation of metric from the flat spacetime. The decoherence occurs even if the particle is static in the gravitational field.
