Condensed Matter / Biophysics Seminars – Alexander Balatsky (U. Connecticut)

Date November 7, 2022 @ 4:05 pm - 5:00 pm

Quantum Materials and Dark Matter Sound

I will outline the ideas of using quantum matter for dark matter (DM) detection. The lower end of dark matter particles mass make it possible to use collective modes of condensed matter systems for dark matter detection[1,2]. I will outline recent proposal using materials with entangled quantum orders as detectors for DM[3]. I will also outline recent discussion of Dark Matter sound mode as another excitation that can be used for DM detection[4].
