Abstract

We report on a new test of Lorentz invariance performed by comparing the resonance frequencies of two orthogonal cryogenic optical resonators subject to Earth’s rotation over 1   yr. For a possible anisotropy of the speed of light c, we obtain Δθc/c0=(2.6±1.7)×1015. Within the Robertson-Mansouri-Sexl (RMS) test theory, this implies an isotropy violation parameter βδ12=(2.2±1.5)×109, about 3 times lower than the best previous result. Within the general extension of the standard model of particle physics, we extract limits on seven parameters at accuracies down to 1015, improving the best previous result by about 2 orders of magnitude.
