Abstract

We present results from two complementary tests of Lorentz invariance in electrodynamics. The first test is an even parity test, which compares two orthogonal cryogenic sapphire microwave oscillators rotating in the lab. We have now acquired over 1 year of data, allowing us to place independent limits on all eight ke and k0+ parameters. The second test is a rotating odd parity test, which compares the phase shift of two one-way propagating waves that experience different permeability over the length of propagation. A sensitive carrier suppression microwave interferometer is used to obtain highly sensitive phase comparison using a Mach-Zehnder configuration. This experiment is sensitive to the isotropic Lorentz violating parameter k tr, and is the first rotating experiment of this type with the first operation of this experiment seting a limit order SO-6 in a few weeks.
