Developing new tools to search for dark matter

研究了探测来自最初非相对论源的相对论玻色子波的可能性。人们发现，即使天体物理源位于离地球很远的地方，地面实验原则上也能对这种相对论性波敏感。然而，根据所考虑的玻色子模型，由于在地球表面附近筛选这种玻色子波，在地球上的探测可能会很复杂。在这种情况下，更灵敏的方法将涉及使用天基探测器。使用包含空间分离节点的探测器网络，可以明确地确认来自经过相对论玻色子波的地外信号，以及信号源的位置。进一步的研究是为了评估量子传感器网络（包括地面和天基网络）在寻找新物理学方面的可行性。结论是，这样的网络为寻找暗物质和更广泛的黑暗领域提供了重要的机会。例如，与单个原子钟节点相比，原子钟网络的使用可以提高对暗物质的灵敏度，并提供有关时空相关函数的宝贵信息。天基原子钟，例如国际空间站或GPS卫星上的原子钟，可以提供巨大的优势，而不是在地球上进行类似的暗标量场模型实验，在地球表面附近展示屏蔽。

Research was undertaken on the possibility of detecting relativistic bosonic waves that originate from sources which are initially non-relativistic. It was found that terrestrial experiments can in principle be sensitive to such relativistic waves even when the astrophysical sources are located quite far away from Earth. However, depending on the model of bosons considered, detection on Earth may be complicated due to screening of such bosonic waves close to Earth's surface. In this case, significantly more sensitive approaches would involve the use of space-based detectors. The use of networks of detectors containing spatially-separated nodes would allow for unambiguous confirmation of extra-terrestrial signals from passing relativistic bosonic waves and the location of the sources.Further research was undertaken to appraise the feasibility of networks of quantum sensors (including ground- and space-based networks) in searches for new physics. It was concluded that such networks offer significant opportunities in searches for dark matter and the broader dark sector. For example, the use of a network of atomic clocks can boost the sensitivity to dark matter compared with a single atomic-clock node, as well as provide valuable information about the spatio-temporal correlation function. Space-based atomic clocks, e.g. on-board the International Space Station or GPS satellites, can provide an enormous advantage over analogous experiments on Earth in models of dark scalar fields that exhibit screening near Earth's surface.
