Abstract: 
Direct searches for light dark matter and measurement of low energy neutrinos, such as solar pp neutrinos, are well motivated topics in astro-particle physics community. One of the primary observables, which are the electronic recoils in detectors, are more relevant when their energies are the similar order to atomic scales. Therefore, the experimental analysis needs theory predictions of scattering rates between incident particles and atomic electrons, including the atomic structure effects.
    Our collaboration, the Theoretical Dark Matter Collaboration (TDMC), are able to apply state-of-the-art atomic calculations, which are benchmarked with experimental data, to study a number of major reaction channels, with some outputs being used by experimentalists. In this talk, I’d like to present our recent, still in progress, major efforts towards building a comprehensive database of atomic response functions.
