Mechanical systems prepared in quantum non-Gaussian states constitute a new advanced
class of phenomena breaking the laws of classical physics. Specifically, such mechanical …

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 …

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 …

Results are reported from a search for a class of composite dark matter models with feeble
long-range interactions with normal matter. We search for impulses arising from passing …

We experimentally demonstrate the stable trap** of a permanent magnet sphere above a
lead superconductor, at vacuum pressures of 4× 10− 8 mbar. The levitating magnet behaves …

We report an experimental observation of a record-breaking ultrahigh rotation frequency
about 6 GHz in an optically levitated nanoparticle system. We optically trap a nanoparticle in …

Despite the unquestionable empirical success of quantum theory, witnessed by the recent
uprising of quantum technologies, the debate on how to reconcile the theory with the …

All three motional modes of a charged dielectric nanoparticle in a Paul trap are cooled
simultaneously by direct feedback to temperatures of a few millikelvins. We test two …

Levitated nano-oscillators are promising platforms for testing fundamental physics and
quantum mechanics in a new high mass regime. Levitation allows extreme isolation from the …

The continuous spontaneous localization (CSL) model predicts a tiny break of energy
conservation via a weak stochastic force acting on physical systems, which triggers the …
