Phys. Rev. Lett. 99, 050401 (2007) [4 pages]Tests of Relativity by Complementary Rotating Michelson-Morley ExperimentsReceived 4 April 2007; published 30 July 2007 We report relativity tests based on data from two simultaneous Michelson-Morley experiments, spanning a period of more than 1 yr. Both were actively rotated on turntables. One (in Berlin, Germany) uses optical Fabry-Perot resonators made of fused silica; the other (in Perth, Australia) uses microwave whispering-gallery sapphire resonators. Within the standard model extension, we obtain simultaneous limits on Lorentz violation for electrons (5 coefficients) and photons (8) at levels down to 10-16, improved by factors between 3 and 50 compared to previous work. © 2007 The American Physical Society URL:
