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 …

By isolating from the environment and precisely controlling mesoscopic objects, levitation in
vacuum has evolved into a versatile technique that has already benefited diverse scientific …

We present experimental results on optical trapping of Yb-doped β-NaYF subwavelength-
thickness high-aspect-ratio hexagonal prisms with a micron-scale radius. The prisms are …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

Quantum theory is incredibly successful, explaining the microscopic world with great
accuracy, from the behaviour of subatomic particles to chemical reactions to solid-state …

We experimentally demonstrate the stable trapping of a permanent magnet sphere above a
lead superconductor, at vacuum pressures of 4× 10− 8 mbar. The levitating magnet behaves …

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

We propose and theoretically analyze an experiment where displacement sensing of an
optically levitated nanoparticle in front of a surface can be used to measure the induced …

Optomechanics, the study of the mechanical interaction of light with matter, has proven to be
a fruitful area of research that has yielded many notable achievements, including the direct …
