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 …

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 …

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 …

The hallmark of quantum physics is Planck's constant h, whose finite value entails the
quantization that gave the theory its name. The finite value of h gives rise to inevitable zero …

We implement a cold-damping scheme to cool one mode of the center-of-mass motion of an
optically levitated nanoparticle in ultrahigh vacuum (10-8 mbar) from room temperature to a …

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 experimentally realize cavity cooling of all three translational degrees of motion of a
levitated nanoparticle in vacuum. The particle is trapped by a cavity-independent optical …
