Description

As the search for dark matter continues down to lower and lower masses, the kinematics of sub-GeV dark
matter scattering require moving beyond the approximation of free-particle scattering. I will describe two inelastic
channels relevant for sub-GeV dark matter detection which necessarily involve the condensed matter properties of
common detector materials: the Migdal effect in liquid nobles, and plasmon excitation in semiconductors. I will
outline the theoretical basis for these processes, discuss the importance of many-body effects in accurately
predicting the scattering rates, and speculate on whether these processes have already been observed at numerous
experiments.
