Force sensing with an optically levitated charged nanoparticle
David Hempston, Jamie Vovrosh, Marko Toroš +3
Levitated optomechanics is showing potential for precise force measurements. Here, we report a case study, to show experimentally the capacity of such a force sensor. Using an elec…
Experimental Realisation of a Thermal Squeezed State of Levitated Optomechanics
Muddassar Rashid, Tommaso Tufarelli, James Bateman +4
We experimentally squeeze the thermal motional state of an optically levitated nanosphere, by fast switching between two trapping frequencies. The measured phase space distribution…
Parametric Feedback Cooling of Levitated Optomechanics in a Parabolic Mirror Trap
Jamie Vovrosh, Muddassar Rashid, David Hempston +3
We demonstrate a simple and robust geometry for optical trapping in vacuum of a single nanoparticle based on a parabolic mirror and the optical gradient force, and we demonstrate r…
