论文摘要
通过将石英振荡器的频率与$^{87} $ rb中的超精细结构过渡的频率进行比较，搜索标量和伪尺度超轻质玻色物质（UBDM）的影响。我们在标量UBDM字段和标准模型（SM）字段之间的线性相互作用限制了$ 1 \ 1 \ times10^{ - 17} -8.3 \ times10^\ times10^{ - 13} $ ev和Quadratic field范围与$ 5 {$ 5 { 4.1 \ times10^{ - 13} $ ev。在各个范围的区域内，我们对线性相互作用的限制显着改善了先前，直接搜索原子参数的振荡，而对二次相互作用的限制超过了这种直接搜索以及天文学观察的限制。
The effects of scalar and pseudoscalar ultralight bosonic dark matter (UBDM) were searched for by comparing the frequency of a quartz oscillator to that of a hyperfine-structure transition in $^{87}$Rb, and an electronic transition in $^{164}$Dy. We constrain linear interactions between a scalar UBDM field and Standard-Model (SM) fields for an underlying UBDM particle mass in the range $1\times10^{-17}-8.3\times10^{-13} $ eV and quadratic interactions between a pseudoscalar UBDM field and SM fields in the range $5\times10^{-18}- 4.1\times10^{-13} $ eV. Within regions of the respective ranges, our constraints on linear interactions significantly improve on results from previous, direct searches for oscillations in atomic parameters, while constraints on quadratic interactions surpass limits imposed by such direct searches as well as by astrophysical observations.
