Novel direct detection constraints on light dark matter
TL;DR: In this paper, the authors derive novel constraints from the inevitable existence of a subdominant, but highly energetic, component of particle dark matter generated through collisions with cosmic rays, which limits the DM-nucleon scattering cross-section to be below the threshold for both spinindependent and spindependent scattering of light DM.

Abstract: All attempts to directly detect particle dark matter (DM) scattering on nuclei suffer from the partial or total loss of sensitivity for DM masses in the GeV range or below. We derive novel constraints from the inevitable existence of a subdominant, but highly energetic, component of DM generated through collisions with cosmic rays. Subsequent scattering inside conventional DM detectors, as well as neutrino detectors sensitive to nuclear recoils, limits the DM-nucleon scattering cross section to be below ${10}^{\ensuremath{-}31}\text{ }\text{ }{\mathrm{cm}}^{2}$ for both spin-independent and spin-dependent scattering of light DM.

Detection Prospects of Dark Matter in Einstein Telescope
TL;DR: In this article, the authors improved the calculations of the elastic motion induced by the dark matter hits on the surface of the mirror equipped with the interferometer for gravitational wave detection and focused on the discovery potential of such a dark matter signal on the third-generation European gravitational wave detector, the Einstein Telescope.

Dark matter direct detection with quantum dots
24 May 2023
TL;DR: In this article , the authors proposed using quantum dots as novel targets to probe sub-GeV dark matter-electron interactions, which can generate one or more electron-hole pairs (excitons), with the multiexciton state decaying via the emission of two photons with an efficiency of about 10% of the single-photon quantum yield.
