Dark matter detection with atomic systems

The mystery of dark matter (DM) is a long-standing issue in physics, with numerous dedicated experiments returning no confirmed detections. As many direct detection experiments rely on catching signals of nuclear recoil, these types of experiments are not applicable to many DM models. Instead, we can utilise the precision that atomic physics allows to search for potential interactions between atomic systems and DM, with possibilities spanning a large mass range. For the higher end of this mass range, we can look for signals of ionisation from DM scattering on or being absorbed by atomic electrons. For the ultralight masses, where DM behaves like a classical field, we can measure the effects in atomic clocks and in variations of fundamental constants. In this talk, I will discuss the prospect for DM detection with atomic systems and the tools needed to accurately assess the possibility.
