Comment on "Test of constancy of speed of light with rotating cryogenic optical resonators"

Abstract

A recent experiment by Antonini et. al. [Phys. Rev. A {\bf 71}, 050101R 2005], set new limits on Lorentz violating parameters in the frame-work of the photon sector of the Standard Model Extension (SME), ${\tilde{\kappa }}_{e-}^{ZZ}$, and the Robertson-Mansouri-Sexl (RMS) framework, $\beta -\delta -1/2$. The experiment had significant systematic effects caused by the rotation of the apparatus which were only partly analysed and taken into account. We show that this is insufficient to put a bound on ${\tilde{\kappa }}_{e-}^{ZZ}$ and the bound on $\beta -\delta -1/2$ represents a five-fold improvement not a ten-fold improvement as claimed.
