All-optical sub-Kelvin sympathetic cooling of a levitated microsphere in vacuum
arXiv:2210.01458 · doi:10.1364/OPTICA.466337
Abstract
We demonstrate all-optical sympathetic cooling of a laser-trapped microsphere to sub-Kelvin temperatures, mediate by optical binding to a feedback-cooled adjacent particle. Our study opens prospects for multi-particle quantum entanglement and sensing in levitated optomechanics.
