Observation of radiation torque shot noise on an optically levitated nanodumbbell
Fons van der Laan, René Reimann, Felix Tebbenjohanns +3
According to quantum theory, measurement and backaction are inextricably linked. In optical position measurements, this backaction is known as radiation pressure shot noise. In ana…

Optically levitated rotor at its thermal limit of frequency stability
Fons van der Laan, René Reimann, Andrei Militaru +4
Optically levitated rotors are prime candidates for torque sensors whose precision is limited by the fluctuationsof the rotation frequency. In this work we investigate an optically…
