Abstract: Advances in low noise cryogenic amplifiers and the commercialization of microwave technology have enabled a new generation of physics experiments that can explore fundamental physics at low energies with exquisite sensitivity. I will discuss two such experiments.
The Axion Dark Matter Experiment (ADMX) uses resonant cavities to search for the axion, a compelling dark matter candidate that has its roots in the strong force.
Project 8 is an experiment which aims to measure cyclotron radiation from tritium beta decay electrons to probe the mass of the neutrino.
Both experiments rely on microwave receivers operating at frequencies commonly used in cellphones, but with noise figures at the edge of what is permitted by quantum mechanics.
