Title: Materials Science Meets Dark Matter Detection: TOORAD!

Abstract:
I will describe an idea I have been working on recently, which proposes to use a novel class of materials known as “Antiferromagnetic Topological Insulators” to detect axion-like dark matter in meV/THz (TOpOlogical Resonant Axion Detection: TOORAD). I will outline the physics case for axion dark matter, particularly in THz, and the associated technological challenges. I’ll then introduce the novel materials, and how they overcome the problems of THz detection. Finally, I’ll discuss some exciting recent progress on THz spectroscopy of material samples.
