10^{-17}能级洛伦兹不变性的旋转光学腔实验
Rotating optical cavity experiment testing Lorentz invariance at the 10^{-17} level
摘要：
本文提出了一种改进的实验室方法，即通过检验光速的各向同性来检验电动力学中的洛仑兹不变性。我们的测量比较了两个正交的光学谐振器的谐振频率，这两个光学谐振器在一块熔融石英中实现，并在精密的空气轴承转盘上连续旋转。对一年内记录的数据进行分析，得出光速各向异性的极限为Δc/c ~ 1 x 10^{-17}。这构成了迄今为止对$c$各向同性的最精确的实验室测试，并且允许将粒子物理学的标准模型的洛伦兹违反扩展的参数约束到10^{-17}的水平。
英文摘要：
We present an improved laboratory test of Lorentz invariance in electrodynamics by testing the isotropy of the speed of light. Our measurement compares the resonance frequencies of two orthogonal optical resonators that are implemented in a single block of fused silica and are rotated continuously on a precision air bearing turntable. An analysis of data recorded over the course of one year sets a limit on an anisotropy of the speed of light of Δc/c ~ 1 x 10^{-17}. This constitutes the most accurate laboratory test of the isotropy of $c$ to date and allows to constrain parameters of a Lorentz violating extension of the standard model of particle physics down to a level of 10^{-17}.
