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 …

Arrays of optically trapped nanoparticles have emerged as a platform for the study of
complex nonequilibrium phenomena. Analogous to atomic many-body systems, one of the …

Phonon lasers, which exploit coherent amplifications of phonons, are a means to explore
nonlinear phononics, image nanomaterial structures and operate phononic devices …

We describe a variety of searches for new physics beyond the standard model of particle
physics which may be enabled in the coming years by the use of optically levitated masses …

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

Motional control of levitated nanoparticles relies on either autonomous feedback via a cavity
or measurement-based feedback via external forces. Recent demonstrations of the …

We propose to optimally control the harmonic potential of a levitated nanoparticle to
quantum delocalize its center-of-mass motional state to a length scale orders of magnitude …

Results are reported from a search for a class of composite dark matter models with feeble
long-range interactions with normal matter. We search for impulses arising from passing …
