Quantum limit of photothermal cooling
arXiv:1011.6295 · doi:10.1103/PhysRevA.83.033809
Abstract
We study the problem of cooling a mechanical oscillator using the photothermal (bolometric) force. Contrary to previous attempts to model this system, we take into account the noise effects due to the granular nature of photon absorption. This allows us to tackle the cooling problem down to the noise dominated regime and to find reasonable estimates for the lowest achievable phonon occupation in the cantilever.
