Laser cooling of mechanical degrees of freedom is one of the most significant achievements in the field of ***,we report,for the first time to the best of our knowledge,efficient passive optomechanical cooling of the motion of a freestanding waveguide coupled to a whispering gallery-mode(WGM)*** waveguide is an 8 mm long glass-fiber nanospike,which has a fundamental flexural resonance atΩ/2π=2.5 kHz and a Q-factor of 1.2×10^*** launching^250μW laser power at an optical frequency close to the WGM resonant frequency,we observed cooling of the nanospike resonance from room temperature down to 1.8 *** cooling of the first higher-order mechanical mode is also *** strong suppression of the overall Brownian motion of the nanospike,observed as an 11.6 dB reduction in its mean square displacement,indicates strong optomechanical stabilization of linear coupling between the nanospike and the cavity *** cooling is caused predominantly by a combination of photothermal effects and optical forces between nanospike and WGM *** results are of direct relevance in the many applications of WGM resonators,including atom physics,optomechanics,and sensing.

Optically levitated micro-and nanoparticles offer an ideal playground for investigating photon–phonon interactions over macroscopic *** we report the observation of long-range optical binding of multiple levitated microparticles,mediated by intermodal scattering and interference inside the evacuated core of a hollow-core photonic crystal fibre(HC-PCF).Three polystyrene particles with a diameter of 1μm are stably bound together with an inter-particle distance of~40μm,or 50 times longer than the wavelength of the trapping *** levitated boundparticle array can be translated to-and-fro over centimetre distances along the *** evacuated to a gas pressure of 6 mbar,the collective mechanical modes of the bound-particle array are able to be *** measured interparticle distance at equilibrium and mechanical eigenfrequencies are supported by a novel analytical formalism modelling the dynamics of the binding *** HC-PCF system offers a unique platform for investigating the rich optomechanical dynamics of arrays of levitated particles in a well-isolated and protected environment.
