双通环形光腔对洛伦兹破坏的新限制
New Limit on Lorentz Violation Using a Double-Pass Optical Ring Cavity
摘要：
通过测量光学环形腔两个反向传播方向的谐振频率差，研究了电动力学中的洛仑兹破坏。我们的腔包含一个介电元件，这使得我们的腔对破坏敏感。激光器频率稳定到腔的逆时针谐振，并且透射光被反射回腔中以用于与顺时针谐振的谐振频率比较。这种双通配置实现了零实验，并提供了对环境干扰的高共模抑制。我们没有发现在$δc /c \lesssim 10^{-14}$水平的奇宇称各向异性的证据。在标准模型扩展的框架内，我们的结果提出了超过5倍更好的限制三个奇奇偶参数$\tildeκ^{JK}_{o+}$和12倍更好的限制标量参数$\tildeκ_{\tr}$相比，以前的最佳限制。
英文摘要：
A search for Lorentz violation in electrodynamics was performed by measuring the resonant frequency difference between two counterpropagating directions of an optical ring cavity. Our cavity contains a dielectric element, which makes our cavity sensitive to the violation. The laser frequency is stabilized to the counterclockwise resonance of the cavity, and the transmitted light is reflected back into the cavity for resonant frequency comparison with the clockwise resonance. This double-pass configuration enables a null experiment and gives high common mode rejection of environmental disturbances. We found no evidence for odd-parity anisotropy at the level of $δc /c \lesssim 10^{-14}$. Within the framework of the Standard Model Extension, our result put more than 5 times better limits on three odd-parity parameters $\tildeκ^{JK}_{o+}$ and a 12 times better limit on the scalar parameter $\tildeκ_{\tr}$ compared with the previous best limits.
