It is possible that bosonic dark matter forms halos around the Sun or the Earth. We discuss the possibility of probing such halos with atomic clocks. Focusing on either a Higgs portal or photon portal interaction between the dark matter and the Standard Model, we search the possible parameter space for which a clock on Earth and a clock in space would have a discernible frequency difference. Bosonic dark matter halos surrounding the Earth can potentially be probed with current optical atomic… Expand

Search for domain wall dark matter with atomic clocks on board global positioning system satellites
A stronger constraint is determined on the coupling of this dark matter to atomic clocks on board global positioning satellites through the analysis of 16 years of archival data, which improves the limits on certain quadratic scalar couplings of domain wall dark Matter to standard model particles by several orders of magnitude.
