We present new results from our test of Lorentz invariance, which compares two orthogonal cryogenic sapphire microwave oscillators rotating in the lab. We have now acquired over 1 year of data, allowing us to avoid the short data set approximation (less than 1 year) that assumes no cancellation occurs between the {kappa}-tilde{sub e-} and {kappa}-tilde{sub o+} parameters from the photon sector of the standard model extension. Thus, we are able to place independent limits on all eight {kappa… CONTINUE READING
