Dirac materials, because of unique symmetries near the Fermi surface, are a promising target for dark photon-mediated scattering and absorption of light dark matter. In this paper, we characterize the daily modulation rate of dark matter interacting with a Dirac material due to anisotropies in the crystal structure of typical Dirac materials, and we show that daily modulation is ${\cal O}(1)$ of the total rate for the Dirac material ZrTe$_5$. These modulation effects depend on the orientation… Expand
