The equivalence principle in classical and quantum physics
Abstract
We test nonmetric theories of gravity using data from the polarization of radio galaxies and from atomic anisotropy experiments. The former leads to a constraint on gravity-induced birefringence that is eight orders of magnitude more precise than previous ones. The data we analyze constrains all but two non-metric degrees of freedom encompassed by the $\chi g$ formalism. Finally, we show that curvature-induced birefringence can be constrained by pulsar timing data.
