Levitation of nanodiamonds is a promising platform for spin-optomechanics experiments and the study of quantum physics at the mesoscale.
However, the temperature of levitated particles in optical tweezers, especially diamonds, is an essential element of this goal, and its characterization is crucial.
In a recent paper by F. Rivière, T. De Guillebon et al. we study the heating of levitated nanodiamonds, using atomic defects of the diamond lattice as a nanothermometer. We demonstrate that the heating comes from the whole diamond volume, highlighting the importance of diamond quality for levitation experiments.
