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 …

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

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 …

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

We discuss effects of loss of coherence in low energy quantum systems caused by or related
to gravitation, referred to as gravitational decoherence. These effects, resulting from random …

The coupling of a levitated submicron particle and an optical cavity field promises access to
a unique parameter regime both for macroscopic quantum experiments and for high …

Rotations of microscale rigid bodies exhibit pronounced quantum phenomena that do not
exist for their centre-of-mass motion. By levitating nanoparticles in ultra-high vacuum …

The physics of low-energy quantum systems is usually studied without explicit consideration
of the background spacetime. Phenomena inherent to quantum theory in curved spacetime …

We report three-dimensional (3D) cooling of a levitated nanoparticle inside an optical cavity.
The cooling mechanism is provided by cavity-enhanced coherent scattering off an optical …
