Baker, Barrett, Brown, Heeger, Lamoreaux, Lehnert, Maruyama
Experiments: ALPHA, HAYSTAC, RAY
Science Goal: Search for axion dark matter using quantum and microwave technologies.
Heeger Group Involvement: Yale is the experimental site and is responsible for systems engineering, cryogenics, and the overall design, construction, operations, data taking, and data analysis of the experiment.

Quantum sensors for neutrinoless double beta decay
Heeger, Maruyama
Experiments: CUORE, CUPID
Science Goal: Develop quantum sensors to search for neutrinoless double beta decay, which could answer why we live in a Universe of matter, not antimatter.
Heeger Group Involvement: The Yale team is developing light detectors for CUPID using quantum sensors that will significantly increase the discovery sensitivity of the detector.
