occupancy as low as possible starting from room temperature… , har feedback cooling vist sig som …

… for which we find we can cool from room temperature to a value of T fb = 11.6 ± 0.1 K. Note
that the second term in Eq. (5) arises due to the fact that feeding back imprecision noise onto …

… Levitated nanoparticles are extremely well isolated from their environment, opening up
the possibility for very long decoherence times and ground state cooling in room temperature …

… In conclusion, we have parametrically feedback cooled all three libration modes of an
optically levitated anisotropic nanoparticle from room temperature to below 16 mK. In particular, …
