| Summary:
We perform the first high-throughput search and evaluation of materials that
can serve as excellent low-mass dark matter detectors. Using properties of
close to one thousand materials from the Materials Project database, we project
the sensitivity in dark matter parameter space for experiments constructed from
each material, including both absorption and scattering processes between dark
matter and electrons. Using the anisotropic materials in the dataset, we
further compute the level of daily modulation in interaction rates and the
resulting directional sensitivities, highlighting materials with prospects to
detect the dark matter wind. Our methods provide the basic tools for the
data-driven design of dark matter detectors, and our findings lay the
groundwork for the next generation of highly optimized direct searches for dark
matter as light as the keV scale.
