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 …

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 …

Optical tweezers are tools made of light that enable contactless pushing, trapping, and
manipulation of objects, ranging from atoms to space light sails. Since the pioneering work …

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 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 …

Controlling the motional degrees of isolated, single nanoparticles trapped within optical
fields in a high vacuum are seen as ideal candidates for exploring the limits of quantum …

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 …

Rotational optomechanics strives to gain quantum control over mechanical rotors by
harnessing the interaction of light and matter. We optically trap a dielectric nanodumbbell in …

Control of the potential energy and free evolution lie at the heart of levitodynamics as key
requirements for sensing, wave function expansion, and mechanical squeezing protocols …

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