论文摘要
宇宙常数提出了物理学中最令人着迷，最混杂的问题之一。对量子力学和一般相对论的直接，看似强大的预测是真空能量吸引人。因此，宇宙常数应该是巨大的。它很小。由于对宇宙常数这么小的原因没有理解，因此在许多不同情况下测试这一想法很重要。特别是，鉴于天文学和粒子物理学的距离的跨度，至关重要的是，在尽可能多的距离尺度上测试真空能量的引力。 Rydberg Atoms开辟了一套新的探索距离。用原子测量宇宙常数是令人满意的，但是其主要意义是将测量值扩展到微观距离。在这里，也没有证据表明真空吸引力。在微米且更少的尺度上，我们将限制为$ 7 $ GEV的限制在引力真空能量的尺度上，远低于粒子物理SM的$ 100 $ GEV的比例。
The cosmological constant presents one of the most fascinating and confounding problems in physics. A straightforward, seemingly robust prediction of quantum mechanics and general relativity is that the vacuum energy gravitates. Therefore, the cosmological constant should be enormous. It is minuscule. Since there is no understanding of why the cosmological constant is so small, it is important to test this idea in many different situations. In particular, given the span of distances in astronomy and particle physics, it is vital to test the gravitation of vacuum energy on as many distance scales as we can. Rydberg atoms open up a new set of distances for exploration. It is satisfying to measure the cosmological constant with an atom, but its main significance is extending measurements to microscopic distances. Here, too, there is no evidence of the gravitation of the vacuum. At scales of a micron and less, we place a limit of $7$ GeV on the scale of gravitating vacuum energy, well below the scale of $100$ GeV of the SM of particle physics.
