Logarithmic Wavelets for Dark Matter--Phonon Scattering
Xu-Xiang Li, Zhengkang Zhang
Phonon excitations in crystals are a promising detection channel for sub-GeV dark matter (DM), and anisotropic targets add directional sensitivity through the daily modulation of t…

Astrophysical Uncertainties in Sub-GeV Dark Matter Detection via Single Phonon Excitations
Xu-Xiang Li, Navaneetha Valsan, Zhengkang Zhang
We present the first systematic study of how local dark matter velocity distribution uncertainties propagate into direct detection rates for dark matter--single phonon scattering.…
