All-electron dark matter-electron scattering with random-phase approximation dielectric screening and local field effects
Cyrus Dreyer, Rouven Essig, Marivi Fernandez-Serra +2
Accurate predictions for dark matter-electron scattering in solids require an all-electron treatment together with a faithful description of dielectric screening beyond simple appr…

SENSEI: First Direct-Detection Results on sub-GeV Dark Matter from SENSEI at SNOLAB
SENSEI Collaboration, Prakruth Adari, Itay M. Bloch +34
We present the first results from a dark matter search using six Skipper-CCDs in the SENSEI detector operating at SNOLAB. We employ a bias-mitigation technique of hiding approximat…

Collective excitations and low-energy ionization signatures of relativistic particles in silicon detectors
Rouven Essig, Ryan Plestid, Aman Singal
Solid-state detectors with a low energy threshold have several applications, including searches of non-relativistic halo dark-matter particles with sub-GeV masses. When searching f…
