Test of constancy of speed of light with rotating cryogenic optical resonators
Abstract
A test of Lorentz invariance for electromagnetic waves was performed by comparing the resonance frequencies of two optical resonators as a function of orientation in space. In terms of the Robertson-Mansouri-Sexl theory, we obtain β-δ-1/2=(+0.5±3±0.7)×10-10 , a tenfold improvement compared to the previous best results. We also set a first upper limit for a parameter of the standard model extension test theory, ∣(κ∼e-)ZZ∣<2×10-14 .
