Levitated optomechanics has great potential in precision measurements, thermodynamics,
macroscopic quantum mechanics, and quantum sensing. Here we synthesize and optically …

We report on rotating an optically trapped silica nanoparticle in vacuum by transferring spin
angular momentum of light to the particle's mechanical angular momentum. At sufficiently …

Rotational optomechanics strives to gain quantum control over mechanical rotors by
harnessing the interaction of light and matter. We optically trap a dielectric nanodumbbell in …

Optical trap** is the craft of manipulating objects with light. Decades after its first inception
in 1970, the technique has become a powerful tool for ultracold‐atom physics and …

The momentum carried by structured light fields exhibits a rich array of surprising features. In
this work, we generate transverse orbital angular momentum (TOAM) in the interference field …

When two or more objects move relative to one another in vacuum, they experience a drag
force, which, at zero temperature, usually goes under the name of quantum friction. This …

Undoubtedly, laser tweezers are the most recognized application of optically induced
mechanical action. Their operation is usually described in terms of conservative forces …
