Subject: From Single-Electron Resolution Phonon-Mediated Detectors To Directional Dark Matter Searches
THIS SEMINAR IS CANCELLED due to illness - To be rescheduled next semester

Direct detection dark matter experiments are striving to develop technologies that allow for ultra low-threshold large modular mass detectors. After a brief overview of the current efforts in the field, I will discuss our new studies suggesting that at the quantum electronic excitation level, solid state detectors exhibit significant directional sensitivity to DM interactions. The solar neutrino-nucleus elastic coherent scattering will soon become the irreducible background for direct detection experiments. Directional sensitivity offers a solution to further gain in DM sensitivity beyond this so called "neutrino floor".
