Title: Electromagnetic searches for axion dark matter
Host: Da Liu
Room: 432

Abstract: Axions, and in particular the QCD axion, are a well-motivated dark matter candidate. They can generically couple to electromagnetic fields, and this coupling is the basis for many dark matter detection experiments, such as ADMX. In this seminar, I’ll talk about the theoretical limits on such experiments — how small a dark matter coupling could they detect, given the limits imposed by quantum mechanics? As well as giving some insights into what can and can’t help, these calculations motivate new approaches to axion dark matter detection, both at low masses (using microwave cavities) and high masses (using photonic materials).
