Description
Understanding energy transport in low-temperature detectors is essential for rare-event searches, quantum sensing applications, and studies of radiation-induced effects in matter. In this work, we extend the G4CMP framework to describe charge transport in sapphire, motivated by applications in dark matter searches and cryogenic radiation detection. For sapphire, a material of growing interest in quantum information science, we develop and calculate the relevant charge transport parameters, incorporating anisotropic hole dynamics, polaron transport, and downconversion processes of charge carriers into polarons with associated phonon emission, together with low-temperature scattering mechanisms governed by Fröhlich coupling. These new capabilities provide a comprehensive foundation within G4CMP for simulating radiation-induced effects in cryogenic detectors, quantum information systems, and sensing applications, with direct relevance to dark matter detection experiments.
