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 …

The ability to accurately control the dynamics of physical systems by measurement and
feedback is a pillar of modern engineering. Today, the increasing demand for applied …

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 …

The field of cavity optomechanics is reviewed. This field explores the interaction between
electromagnetic radiation and nanomechanical or micromechanical motion. This review …

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 …

Quantum mechanics is an extremely successful theory that agrees with every experimental
test. However, the principle of linear superposition, a central tenet of the theory, apparently …

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 …

Optical laser fields have been widely used to achieve quantum control over the motional and
internal degrees of freedom of atoms and ions,, molecules and atomic gases. A route to …

We optically trap a single nanoparticle in high vacuum and cool its three spatial degrees of
freedom by means of active parametric feedback. Using a single laser beam for both …
