Snowmass2021 Cosmic Frontier: The landscape of low-threshold dark matter
  direct detection in the next decade
  The search for particle-like dark matter with meV-to-GeV masses has developed
rapidly in the past few years. We summarize the science case for these
searches, the recent progress, and the exciting upcoming opportunities. Funding
for Research and Development and a portfolio of small dark matter projects will
allow the community to capitalize on the substantial recent advances in theory
and experiment and probe vast regions of unexplored dark-matter parameter space
in the coming decade.
