NPA Seminar: Yoni Kahn, UIUC, "Dark Matter Meets Condensed Matter"
As the gravitational evidence accumulates inexorably that dark matter comprises the vast majority of the mass of the universe, the particle nature of dark matter remains a mystery. New laboratory experiments are being commissioned to probe sub-GeV dark matter, but the signatures in these detectors rely crucially on the condensed matter properties of the detector material. Similarly, detecting the couplings of axions to matter requires considering collective modes in materials.
