项目摘要

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.

对探测起源于最初非相对论源的相对论玻色子波的可能性进行了研究。人们发现，即使天体物理源位于离地球相当远的地方，地面实验原则上也可以对这种相对论波敏感。然而，根据所考虑的玻色子模型，在地球上的探测可能会很复杂，因为在地球表面附近会屏蔽这种玻色子波。在这种情况下，灵敏度高得多的办法将涉及使用天基探测器。使用含有空间分离节点的探测器网络将能够明确确认来自通过的相对论玻色子波的地外信号和源的位置，还进行了进一步的研究，以评估量子传感器网络（包括地面和空间网络）在寻找新物理学方面的可行性。得出的结论是，这种网络为寻找暗物质和更广泛的暗区提供了重要的机会。例如，与单个原子钟节点相比，使用原子钟网络可以提高对暗物质的灵敏度，并提供有关时空相关函数的有价值的信息。天基原子钟，例如国际空间站或全球定位系统卫星上的原子钟，可以在地球表面附近显示屏蔽的暗标量场模型中提供比地球上的类似实验更大的优势。
