The Search for Wavy Dark Matter: Axions ABRACADABRA to DMRadio

The particle nature of dark matter remains one of the great open questions in physics.There is a broad category of candidates whose mass is so light that they behave more as waves than as particles. The most well-known is the axion, which has had a renaissance as a dark matter candidate as theoretical studies have improved our understanding of axion cosmology and advances in quantum sensing and cryogenics have opened new opportunities for detection. In this talk,I will present an overview of the field of wavy dark matter and with a focus on my work to realize a definitive search for GUT-scale axions with the DMRadio program and the ABRACADABRA demonstrator.
