Modern Michelson-Morley Experiment using Cryogenic Optical Resonators
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)×10-15. Within the Robertson-Mansouri-Sexl (RMS) test theory, this implies an isotropy violation parameter β-δ-1/2=(-2.2±1.5)×10-9, 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 10-15, improving the best previous result by about 2 orders of magnitude.
