This project aims to propose new enhanced effects of hypothetical dark matter particles in atomic and astrophysical phenomena, perform calculations, and motivate new experiments with a higher sensitivity to these particles. The mass of dark matter in the Universe is five times that of ordinary matter, yet its nature is still unknown. This project also aims to improve calculations of the effects of dark matter searched for in underground laboratories including the Australian Stawell laboratory. Relativistic and many-body effects may change the results by orders of magnitude, and proper account of them is important. This may be achieved using our computer codes for high-precision relativistic atomic many-body calculations.

该项目旨在提出假想暗物质粒子在原子和天体物理现象中的新增强效应，进行计算，并激发对这些粒子具有更高灵敏度的新实验。宇宙中暗物质的质量是普通物质的五倍，但它的性质仍然未知。该项目还旨在改进对在地下实验室（包括澳大利亚斯塔韦尔实验室）中搜索的暗物质影响的计算。相对论效应和多体效应可能会改变结果的数量级，适当地考虑它们是很重要的。这可以通过使用我们的高精度相对论原子多体计算的计算机代码来实现。
