We propose hexagonal ice (H$_2$O) as a new target for light dark matter (DM) direct detection. Ice, a polar material, is suitable for single phonon detection through DM scattering for which we consider light dark photon and light scalar mediator models. We report a rate sensitivity down to a DM mass of $\sim$keV, constituting a broader mass range than other promising candidates. We find better sensitivity for near-term experimental thresholds from the presence of high-frequency phonons. These advantages, and ice's availability, make it highly promising for single-phonon detection.

  1. Coherence from interference: a solvable model of sub-GeV dark matter-nucleus scattering

    hep-ph 2026-07 conditional novelty 6.0

    In an exactly solvable 1D lattice, coherent and incoherent DM-nucleus structure factors differ only by a crystal-momentum delta function that becomes unimportant for n≥2 phonons, validating hybrid Inc+LW rate calculations.
