Title: 
OPTIMAL SUBSTRATE FOR DIRECT DETECTION OF LIGHT DARK MATTER

Abstract: 
A common approach to search for dark matter is via direct detection of interaction between hypothesized dark matter particles and some solid state substrate such as silicon or germanium. In recent years a lot of progress has been made with regard to understanding the various condensed matter physics relevant to this type of experiment. In this talk I will discuss some of these progress that I have contributed to. I will first present the various physical processes relevant to the detection of dark matter using solid state cryogenic detectors and then derive criteria for looking for the optimal substrates for the different interaction channels. In particular I will focus on the physics relevant to sub-GeV light dark matter candidates. Towards the end I will also briefly cover some original contributions to the signal processing of cryogenic dark matter detectors.
