Description
Atomic clocks are among the most precise instruments ever made, their precision continues to improve rapidly, reaching the $10^{-19}$ level in relative frequency shift. Existing research on atomic clocks as probes of dark matter (DM) has focused on changes in clock frequency due to interactions with DM particles. In this work, we investigate the ability of atomic clocks to detect the local DM density purely through gravitational effects. We propose several setups of space-borne clock systems, compute detectable local DM overdensities for near-future clock precisions, and compare them with existing bounds.
