Abstract

Anisotropy in the speed of light that has been constrained by Michelson-Morley-type experiments also generates anisotropy in the Coulomb interactions. This anisotropy can manifest itself as an energy anisotropy in nuclear and atomic experiments. Here the experimental limits on Lorentz violation in _{10}^{21}Ne are used to improve the limits on Lorentz symmetry violations in the photon sector, namely, the anisotropy of the speed of light and the Coulomb interactions, by 7 orders of magnitude in comparison with previous experiments: the speed of light is isotropic to a part in 10^{28}.

摘要

已被迈克尔逊 - 莫雷型实验所限制的光速各向异性，也会在库仑相互作用中产生各向异性。这种各向异性在核与原子实验中会表现为能量各向异性。在此，利用对(^{21}_{10}Ne)中洛伦兹违反的实验限制，相较于先前实验，将光子领域中洛伦兹对称性违反的限制，即光速和库仑相互作用的各向异性，提高了7个数量级：光速的各向同性达到(10^{28})分之一。
