Static force characterization with Fano anti-resonance in levitated optomechanics
Chris Timberlake, Marko Toroš, David Hempston +3
We demonstrate a classical analogy to the Fano anti-resonance in levitated optomechanics by applying a DC electric field. Specifically, we experimentally tune the Fano parameter by…
Precession Motion in Levitated Optomechanics
Muddassar Rashid, Marko Toroš, Ashley Setter +1
We investigate experimentally the dynamics of a non-spherical levitated nanoparticle in vacuum. In addition to translation and rotation motion, we observe the light torque-induced…
Detection of anisotropic particles in levitated optomechanics
Marko Toroš, Muddassar Rashid, Hendrik Ulbricht
We discuss the detection of an anisotropic particle trapped by an elliptically polarized focused Gaussian laser beam. We obtain the full rotational and translational dynamics, as w…
