论文摘要
一些新的量子重力或暗物质的物理模型可以预测基本常数的漂移或振荡。一个相对简单的模型将分子振动与质子与电子质量比$μ$相关。许多振动过渡都处于光学频率上，可作为高度准确的光学时钟的前景。我们简要介绍了新的物理模型，该模型导致$μ$的变化以及当前对漂移和振荡振幅的限制。经过实验室程序的概述，我们为当前正在开发或正在进行的实验提供了分子的例子。这些实验预计的系统和统计不确定性使他们在下一代搜索$μ$的时间变化时是领先的候选人。
Some new physics models of quantum gravity or dark matter predict drifts or oscillations of the fundamental constants. A relatively simple model relates molecular vibrations to the proton-to-electron mass ratio $μ$. Many vibrational transitions are at optical frequencies with prospects for use as highly accurate optical clocks. We give a brief summary of new physics models that lead to changes in $μ$ and the current limits on drifts and oscillation amplitudes. After an overview of laboratory procedures, we give examples of molecules with experiments currently in development or underway. These experiments' projected systematic and statistical uncertainties make them leading candidates in next-generation searches for time-variation of $μ$.
