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 …

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 …

In this review, the nexus of nanophotonics and quantum science is considered. This nexus
offers a wealth of applications and novel fundamental effects. Such an interdisciplinary …

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 …

We use an optimal control protocol to cool one mode of the center-of-mass motion of an
optically levitated nanoparticle. The feedback technique relies on exerting a Coulomb force …

Continuous weak measurement allows localizing open quantum systems in state space and
tracing out their quantum trajectory as they evolve in time. Efficient quantum measurement …

Nanomechanical resonators are widely operated as force and mass sensors with
sensitivities in the zepto-Newton (10–21) and yocto-gram (10–24) regime, respectively …

We investigate experimentally the dynamics of a nonspherical levitated nanoparticle in a
vacuum. In addition to translation and rotation motion, we observe the light torque-induced …

Navigation, biotracking devices, and gravity gradiometry are among the diverse range of
applications requiring ultrasensitive measurements of acceleration. We describe an …

Recent experiments demonstrate highly tunable nonreciprocal coupling between levitated
nanoparticles due to optical binding [J. Rieser, Science 377, 987 (2022) 0036-8075 …
