Phonon-mediated Migdal effect in semiconductor detectors
Zheng-Liang Liang, Chongjie Mo, Fawei Zheng, Ping Zhang
Abstract
This paper presents a novel treatment of the dark matter induced Migdal effect in solids, providing a full theoretical description of it as a phonon mediated process. This allows the authors to make reliable predictions for dark matter masses below 50 MeV, where the previously used approximation of assuming the nuclei to be freely recoiling breaks down.
