Description
Phonon-mediated detectors have emerged as a promising technology for detecting low-energy particles, including neutrinos through coherent elastic neutrino-nucleus scattering (CEvNS) and dark matter. Coupling phonons with qubit technology, in addition to piezoelectric transducers, enables the realization of highly sensitive quantum acoustic detectors for such particle detection. An important consideration currently is to efficiently transport phonon energy deposited from the particle interaction to the quantum acoustic detector. In this talk, we present our work on the implementation of G4CMP to model phonon and quasiparticle transport and dynamics and investigate how superconducting geometry and relevant device parameters affect phonon transport and collection efficiency. We also specifically incorporated TeO₂ and LiNbO₃ for the first time in G4CMP. These studies will help us design highly sensitive quantum detectors for neutrino detection.
