abstract
We propose and study a new class of superconducting detectors which are sensitive to O(meV) electron recoils from dark matter-electron scattering. Such devices could detect dark matter as light as the warm dark matter limit, mX > keV. We compute the rate of dark matter scattering off of free electrons in a (superconducting) metal, including the relevant Pauli blocking factors. We demonstrate that classes of dark matter consistent with terrestrial and cosmological/astrophysical constraints could be detected by such detectors with a moderate size exposure.

Astrophysical uncertainties in dark matter halo models produce O(1% to 100%) fractional deviations in predicted single-phonon rates, but can be captured by parameter variations within the Standard Halo Model after rms-matching.
Solar-reflected inelastic dark matter produces detectable signals in xenon and semiconductor detectors, enabling new constraints on MeV-scale dark matter parameter space.
Curvature of the angular spectrum of dark matter events in directional 2D detectors encodes the dark matter mass scale.
