Abstract :
We report on a new generation of relativity tests. By frequency comparisons utilizing cryogenic optical resonators (COREs), we confirmed (i) the velocity-independence of the speed of light to a threefold higher accuracy, (ii) local position invariance, and (iii) isotropy of space, with an accuracy 3 times better than the best previous experiment.
