Gravitational Spin Hall Effect in Curves Spacetimes
Abstrak
Geometric optics approximation sufficiently describes the effects in the near-earth environment, and Faraday rotation is purely a reference frame effect in this limit. A simple encoding procedure could mitigate the Faraday phase error. However, the framework of geometric optics is not sufficient to describe the propagation of waves of large but finite frequencies. So, we outline the technique to solve the equations for the propagation of an electromagnetic wave up to the subleading order geometric optics expansion in curved spacetimes. For this, we first need to construct a set of parallel propagated null tetrads in curved spacetimes. Then we should use the parallel propagated tetrad to solve the modified trajectory equation. The wavelength-dependent deviation of the electromagnetic waves is observed, which gives the mathematical description of the gravitational spin Hall effect.
