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 …

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

This paper points out the importance of the assumption of locality of physical interactions,
and the concomitant necessity of propagation of an entity (in this case, off-shell quanta …

We propose to optimally control the harmonic potential of a levitated nanoparticle to
quantum delocalize its center-of-mass motional state to a length scale orders of magnitude …

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 …

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 …

A recently proposed experimental protocol for quantum gravity induced entanglement of
masses (QGEM) requires in principle realizable, but still very ambitious, set of parameters in …

This paper demonstrates cooling of the center-of-mass motion of 10-μ m-diameter optically
levitated silica spheres to an effective temperature of 50±22 μ K, achieved by minimizing the …

A levitated nanomechanical oscillator under ultrahigh vacuum is highly isolated from its
environment. It has been predicted that this isolation leads to very low mechanical …

General relativity is a classical field theory and therefore does not predict gravitationally
induced entanglement. As such, recent proposals have focused on seeking an empirical …
