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 …

Tests of quantum mechanics on a macroscopic scale require extreme control over
mechanical motion and its decoherence,–. Quantum control of mechanical motion has been …

Quantum control of complex objects in the regime of large size and mass provides
opportunities for sensing applications and tests of fundamental physics. The realization of …

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 …

The momentum transfer between a photon and an object defines a fundamental limit for the
precision with which the object can be measured. If the object oscillates at a frequency Ω 0 …

Optically trapped nanospheres in high vacuum experience little friction and hence are
promising for ultrasensitive force detection. Here we demonstrate measurement times …

Quantum physics has intrigued scientists and philosophers alike, because it challenges our
notions of reality and locality—concepts that we have grown to rely on in our macroscopic …

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

Optomechanical cavity cooling of levitated objects offers the possibility for laboratory
investigation of the macroscopic quantum behavior of systems that are largely decoupled …
