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 engineer cavity-mediated interactions has emerged as a powerful tool for the
generation of non-local correlations and the investigation of non-equilibrium phenomena in …

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 …

Optical manipulations utilizing the mechanical effect of light have been indispensable in
various disciplines. Among those various manipulations, optical pulling has emerged …

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 …

We demonstrate optical levitation of SiO 2 spheres with masses ranging from 0.1 to 30 ng. In
high vacuum, we observe that the measured acceleration sensitivity improves for larger …

The traditional view from particle physics is that quantum-gravity effects should become
detectable only at extremely high energies and small length scales. Owing to the significant …
