The Duffing oscillator is a nonlinear extension of the ubiquitous harmonic oscillator and as such plays an outstanding role in science and technology. Experimentally, the system pa…
A chemical nano-reactor based on a levitated nanoparticle in vacuum
Francesco Ricci, Marc T. Cuairan, Andreas W. Schell +4
A single levitated nanoparticle is used as a nano-reactor for studying surface chemistry at the nanoscale. Optical levitation under controlled pressure, surrounding gas composition…
Strong Optomechanical Coupling at Room Temperature by Coherent Scattering
Andrés de los Ríos Sommer, Nadine Meyer, Romain Quidant
Quantum control of a system requires the manipulation of quantum states faster than any decoherence rate. For mesoscopic systems, this has so far only been reached by few cryogenic…
Resolved Sideband Cooling of a Levitated Nanoparticle in the Presence of Laser Phase Noise
