Abstract

We present a new analysis of a recent Michelson-Morley experiment in the photon sector of the Standard-Model Extension (SME). Compared to previous analyses, we extend it to include isotropic deviations of the vacuum speed of light from c, as described by the SME coefficient ktr, in addition to the usual direction-dependent anisotropies in the speed of light. This represents the first constraint on ktr reported by a Michelson-Morley experiment and the first analysis of a single experiment to simultaneously set limits on all nine nonbirefringent terms in the photon sector of the SME.
