Optical trapping describes the interaction between light and matter to manipulate micro-
objects through momentum transfer. In the case of 3D trapping with a single beam, this is …

BACKGROUND Levitation of large objects has become a widely used technique in science
and engineering, and the control of levitated nano-and micro-objects in vacuum has gained …

Optomechanics is concerned with the use of light to control mechanical objects. As a field, it
has been hugely successful in the production of precise and novel sensors, the …

Torque sensors such as the torsion balance enabled the first determination of the
gravitational constant by Henri Cavendish and the discovery of Coulomb's law. Torque …

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 …

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

Since their invention in 1986 by Arthur Ashkin and colleagues, optical tweezers have
become an essential tool in several fields of physics, spectroscopy, biology …

Rotations of microscale rigid bodies exhibit pronounced quantum phenomena that do not
exist for their centre-of-mass motion. By levitating nanoparticles in ultra-high vacuum …

Quantum state preparation of mesoscopic objects is a powerful playground for the
elucidation of many physical principles. The field of cavity optomechanics aims to create …
