Combined feedback and sympathetic cooling of a mechanical oscillator coupled to ultracold atoms
Combined feedback and sympathetic cooling of a mechanical oscillator coupled to ultracold atoms
A promising route to novel quantum technologies are hybrid quantum systems, which combine the advantages of several individual quantum systems. We have realized a hybrid atomic-mechanical experiment consisting of a SiN membrane oscillator cryogenically precooled to 500 mK and optically coupled to a cloud of laser cooled Rb atoms. Here, …
