DESCRIPTION:Title: <a href="https://researchseminars.org/talk/nhetc/14/">D
 ark matter direct detection with dielectrics</a>\nby Tongyan Lin as part o
 f NHETC Seminar\n\n\nAbstract\nDirect detection experiments are rapidly ad
 vancing in the search for sub-GeV dark matter. As energy thresholds become
  lower\, the many-body physics of a target material becomes especially imp
 ortant in determining a dark matter signal. In this talk\, I will discuss 
 how dark matter interactions in dielectric materials can be understood in 
 terms of the dielectric response\, or energy loss function (ELF). This pro
 vides a useful framework for dark matter direct detection and also allows 
 us to calculate some new effects. I will discuss various applications of t
 his\, including screening effects for dark matter electron scattering\, ph
 onon creation\, and the Migdal effect in semiconductors.\n
