The IQC blog “Our quantum world” is finally open. The first blog post is about possible experiments that can detect the effect of Earth’s gravity on photons, check it out.
You can also check out my papers with Daniel Terno and other collaborators on the subject.
Polarization rotation, reference frames, and Mach’s principle
Photon polarization and geometric phase in general relativity
Post-Newtonian gravitational effects in optical interferometry
