Dark Matter Meets Condensed Matter

by Yonatan Kahn (The University of Illinois at Urbana-Champaign)

Tuesday, 5 October 2021 from to (America/Chicago)
Speaker: Dr. Yonatan Kahn (Physics, The University of Illinois at Urbana-Champaign)

Title: Dark Matter Meets Condensed Matter

Abstract: 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 dark matter lighter than the proton mass, but the signatures in these detectors rely crucially on the condensed matter properties of the detector material. I will survey the progress made in understanding existing detectors and designing future ones which operate in this unusual low-energy regime, driven by an incredibly fruitful and rich collaboration between condensed matter physicists and particle physicists, both theorists and experimentalists. I will describe a new approach which helps to identify novel condensed matter systems with optimal material properties for dark matter detection, bridging high- and low-energy physics and ensuring that no stone is left unturned in the hunt for dark matter in the laboratory.

About the speaker: Yonatan Kahn is a theoretical physicist whose research is focused on dark matter and its detection strategies. Currently an assistant professor at the University of Illinois at Urbana-Champaign (UIUC), he previously held postdoctoral positions at the Kavli Institute for Cosmological Physics (KICP) at the University of Chicago and Princeton University. Dr. Kahn received his Ph.D. in 2015 from MIT, under the supervision of Jesse Thaler. He holds degrees in music, physics, and mathematics from Northwestern University (B.A., B.Mus 2009) and completed Part III of the Mathematical Tripos with Distinction at the University of Cambridge in 2010 supported by a Churchill Scholarship. Dr. Kahn was an NSF Graduate Fellow and recipient of the Andrew M. Lockett Memorial Fund Award for Graduate Research at MIT. In 2016 he received the American Physical Society’s J.J. and Noriko Sakurai Dissertation Award in Theoretical Particle Physics.
