Description

Light Dark Matter (LDM) is an interesting and well motivated alternative to WIMP as a dark matter candidate. Because of its light mass, electron recoil could become a better signal for LDM detection than nuclear recoil. We have applied an *ab initio* method, MCRRPA, to atomic ionization by neutrino or LDM to Ge, Xe and other targets with better than 10% accuracy. The neutrino-atom ionization is important to constrain new physics in the neutrino sector and to control the solar neutrino background for experimental collaborations such as LZ and DARWIN. In DM ionization, we have analytically solved the hydrogen case, which serves an important case study for our future *ab initio* calculations using realistic targets.
