# Photon polarization and geometric phase in general relativity

@article{Brodutch2011PhotonPA, title={Photon polarization and geometric phase in general relativity}, author={Aharon Brodutch and Tommaso F. Demarie and Daniel R. Terno}, journal={Physical Review D}, year={2011}, volume={84}, pages={104043} }

Rotation of polarization in an external gravitational field is one of the effects of general relativity that can serve as a basis for its precision tests. A careful analysis of reference frames is crucial for a proper evaluation of this effect. We introduce an operationally-motivated local reference frame that allows for a particularly simple description. We present a solution of null geodesics in Kerr space-time that is organized around a new expansion parameter, allowing a better control of…
