论文摘要
我们搜索诱导精细结构常数的振荡的超轻型标量候选，电子和夸克质量以及量子彩色动力学量表具有$^{171} $ yb光学晶格时钟之间的频率比较数据，$^{133} $^{133} $ cs fount microwave clock plock plock plock plock plock plock plack cast 298 $ up up up up $ up $ up $ up $ up up $ up $ up $ up $ up $ up $ up $ up 15 $ 15。标量暗物质与电子和gluons的耦合的新限制从$ 10^{ - 22} $ ev/$ ev/$ c^{2} $到$ 10^{ - 20} $ ev/$ ev/$ ev/$ c^{2} $，假设这些耦合的每个耦合都是频率比率的主导率。 $^{171} $ yb时钟过渡的绝对频率也被确定为$ 518 \，295 \，836 \，590 \，863.69（28）$ Hz，这是对SI重新定义的重要贡献之一。
We search for ultralight scalar dark matter candidates that induce oscillations of the fine structure constant, the electron and quark masses, and the quantum chromodynamics energy scale with frequency comparison data between an $^{171}$Yb optical lattice clock and a $^{133}$Cs fountain microwave clock that span 298 days with an uptime of 15.4 $\%$. New limits on the couplings of the scalar dark matter to electrons and gluons in the mass range from $10^{-22}$ eV/$c^{2}$ to $10^{-20}$ eV/$c^{2}$ are set, assuming that each of these couplings is the dominant source of the modulation in the frequency ratio. The absolute frequency of the $^{171}$Yb clock transition is also determined as $518\,295\,836\,590\,863.69(28)$ Hz, which is one of the important contributions towards a redefinition of the SI second.
