abstract
We calculate target-material responses for dark matter--electron scattering at the \textit{ab-initio} all-electron level using atom-centered gaussian basis sets. The all-electron effects enhance the material response at high momentum transfers from dark matter to electrons, $q\gtrsim \mathcal{O}\left({10\ \alpha m_e}\right)$, compared to calculations using conventional plane wave methods, including those used in QEDark; this enhances the expected event rates at energy transfers $E \gtrsim 10$~eV, especially when scattering through heavy mediators. We carefully test a range of systematic uncertainties in the theory calculation, including those arising from the choice of basis set, exchange-correlation functional, number of unit cells in the Bloch sum, $\mathbf{k}$-mesh, and neglect of scatters with very high momentum transfers. We provide state-of-the-art crystal form factors, focusing on silicon and germanium. Our code and results are made publicly available as a new tool, called Quantum Chemistry Dark (``QCDark'').

First-principles upper bounds on dark matter-electron scattering rates from condensed matter sum rules
Dark matter-electron scattering rates in isotropic materials are bounded from above by a universal expression depending only on plasma frequency, mass density, and static dielectric function.

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.

Electronic structure of liquid xenon in the context of light dark matter direct detection
Liquid xenon's effect on dark matter-electron scattering can be captured by atomic wave functions combined with a liquid density of states, shifting exclusion limits by up to a factor of two.

Constraints on Sub-MeV Dark Matter from Solar Reflection with DAMIC-M
With ~1.3 kg-day of DAMIC-M skipper-CCD data, solar-reflected dark matter yields 90% CL limits on the DM-electron cross section reaching 3.16e-37 cm2 at 0.1 MeV for an ultralight mediator.

Direct Detection and Cosmological Constraints of Dark Matter with Dark Dipoles
Cosmological and direct-detection data already exclude most sub-GeV dark-matter parameter space for dark-photon magnetic dipole interactions, with semiconductor detectors needed to probe the remaining electric-dipole ...
