Particulate dark matter is a long hypothesized solution to various astrophysical observations seemingly at odds with a completely luminous universe. Despite the success of dark matter in explaining these observations, to date physicists have been unable to conclusively observe its interactions with Standard Model matter directly.

In the direct detection of dark matter with masses down to O(keV), the energies im- parted in the detector become vanishingly small. Many novel ideas have been proposed for instrumenting athermal phonon sensors on Fermi-degenerate materials [1], polar crys- tals [2–4], and CVD diamond [5], requiring detector energy thresholds of O(1−100) meV.

Its gravitational effects are observed on scales ranging from individual galaxies to the cosmic microwave background. Unless there is something peculiar about labs on Earth, dark matter should be detectable in those as well.
