Identifying the nature of dark matter (DM) has long been a pressing question for particle
physics. In the face of ever-more-powerful exclusions and null results from large-exposure …

We study the direct detection prospects for a representative set of simplified models of sub-
GeV dark matter (DM), accounting for existing terrestrial, astrophysical and cosmological …

Numerous astrophysical and cosmological observations are best explained by the existence
of dark matter, a mass density which interacts only very weakly with visible, baryonic matter …

We show that polar materials are excellent targets for direct detection of sub-GeV dark
matter due to the presence of gapped optical phonons as well as acoustic phonons with …

We consider the direct detection of dark matter (DM) with polar materials, where single
production of optical or acoustic phonons gives an excellent reach to the scattering of sub …

Dark matter (DM) particles with mass in the sub-GeV range are an attractive alternative to
heavier weakly interacting massive particles, but direct detection of such light particles is …

We suggest a novel experimental concept for detecting MeV-to-GeV-mass dark matter, in
which the dark matter scatters off electrons in a scintillating target and produces a signal of …

We show that a two-excitation process in superfluid helium, combined with sensitivity to meV
energy depositions, can probe dark matter down to the∼ keV warm dark matter mass limit …

The direct detection of dark matter particles with mass below the GeV scale is hampered by
soft nuclear recoil energies and finite detector thresholds. For a given maximum relative …
