Quantum Sensors for the Hidden Sector is a UK collaboration that is probing axion dark matter. I will motivate axions as a dark matter candidate, discuss the experiement, and present an update on our project.
The axion, as well as being a proposed solution to the strong CP problem, is a well-motivated candidate for dark matter [1]. The Quantum enhanced Particle Astrophysics (QuEPA) project at Imperial College London looks to detect axions with a microwave cavity and trapped electrons. Towards this goal, a dielectric Fabry-Perot cavity has been developed as a dark matter haloscope to convert axions...
Superconducting Parametric Amplifiers (SPAs) have seen great interest in recent years due to their high gain and quantum limited noise performance. Among these amplifiers, resonant SPAs have been widely developed for experiments where ultra low-noise narrow-band amplification is of interest, such as the search for Axion dark matter in particle physics and the detection of spectroscopic lines...
