abstract
The EDELWEISS collaboration has performed a search for Dark Matter (DM) particles interacting with electrons using a 33.4 g Ge cryogenic detector operated underground at the LSM. A charge resolution of 0.53 electron-hole pairs (RMS) has been achieved using the Neganov-Trofimov-Luke amplification with a bias of 78 V. We set the first Ge-based constraints on sub-MeV/c$^{2}$ DM particles interacting with electrons, as well as on dark photons down to 1 eV/c$^2$. These are competitive with other searches. In particular, new limits are set on the kinetic mixing of dark photon DM in a so far unconstrained parameter space region in the 6 to 9 eV/c$^2$ mass range. These results demonstrate the high relevance of cryogenic Ge detectors for the search of DM interactions producing eV-scale electron signals.

Ubiquitous Corotation of Dark Matter Halos: Implications for Direct Detection
Dark matter in simulated Milky Way analogues preferentially corotates with the baryonic disk, suppressing predicted direct-detection rates for light WIMPs, reducing directional modulation, and producing a 21% astrophy...

Direct Detection of Leptophobic Dark Matter with Electronic Collective Excitations
Leptophobic dark matter can excite plasmons in silicon through hadronic loops, and SENSEI data now constrain its nucleon cross section down to ~1e-31 cm^2 in the sub-MeV mass range.

A general upper bound on the light dark matter scattering rate in materials
Using Kramers-Kronig relations, the paper derives a material-independent upper bound on the rate of dark matter induced electronic transitions for couplings to density, spin, and currents, and evaluates how close Ge, ...

Many-body atomic response functions of xenon and germanium for leading-order sub-GeV dark matter-electron interactions in effective field theory
The authors provide full (MC)RRPA atomic response functions for xenon and germanium for sub-GeV dark matter-electron scattering, and report a low-energy spin-dependent response distinct from the spin-independent one.
