Description
Athermal phonons are high-energy vibration modes in solid-state substrates. They are the signal channel for sub-GeV low-mass dark matter direct search, while they are also dangerous noises in quantum information systems. I'll first introduce the method of athermal phonon detection in particle detectors. Then I'll discuss three approaches to mitigate athermal phonons: isolation, down-conversion, and phonon cloaking, inspired by particle and cosmology microwave background detectors.
