Optical potential mapping with a levitated nanoparticle at sub-wavelength distances from a membrane
Rozenn Diehl, Erik Hebestreit, René Reimann +3
The controllable positioning of a vacuum-levitated object near a material surface is of importance for studying short-range forces, such as Casimir forces, interfacial friction for…

GHz Rotation of an Optically Trapped Nanoparticle in Vacuum
René Reimann, Michael Doderer, Erik Hebestreit +5
We report on rotating an optically trapped silica nanoparticle in vacuum by transferring spin angular momentum of light to the particle's mechanical angular momentum. At sufficient…
