We demonstrate quantum ground state cooling of a levitated nanoparticle in a room temperature environment.

Our essay has won the first prize of the Gravity Research Foundation 2019 “Essays on Gravitation” contest.

In this work we demonstrate cavity cooling by coherent scattering, a new paradigm of cavity cooling for levitated optomechanics. Genuine...

We argue that the (linearized) gravitational field of a massive object in a quantum superposition has to exhibit genuine quantum features. More...

In this work, we show near field detection of the motion of a 150 nm silica particle (2 fg, 1e10 a.m.u.) levitated in an optical tweezer.

In this work we demonstrate the violation of a Bell inequality involving a massive, macroscopic mechanical system.
