Superconducting detectors have been proposed as outstanding targets for the direct detection of light dark matter scattering at masses as low as a keV. We study the prospects for directional detection of dark matter in isotropic superconducting targets from the angular distribution of excitations produced in the material. We find that dark matter scattering produces initial excitations with an anisotropic distribution, and further show that this directional information can be preserved as the initial excitations relax. Our results demonstrate that directional detection is possible for a wide range of dark matter masses, and pave the way for light dark matter discovery with bulk superconducting targets.

  1. Dark Matter Weather: Probing Sub-GeV Interactions with Earth-Shielding Modulation

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Daily Earth-shielding modulation of sub-GeV dark matter can separate dark-matter–electron from dark-matter–nucleon scattering, and the isoangle shape statistic provides a new validation handle for liquid-noble detectors.

  2. Unconventional Materials for Light Dark Matter Detection

    hep-ph 2025-07 conditional novelty 6.0 of 10

    TiSe2, Sr2RuO4, and hole-doped diamond are projected to improve sub-MeV dark matter detection reaches by one to three orders of magnitude over existing proposals, with directional sensitivity from their anisotropic responses.
