Feedback cooling of a levitated nanoparticle in a radially polarized vector beam trap
Felipe Almeida, M. Rademacher, J. M. H. Gosling +1
We demonstrate optical levitation and feedback cooling of a silica nanoparticle (radius = 78~nm) trapped within a radial vector beam (RVB) in high vacuum. Radial vector beams, when…
Roto-translational optomechanics
M. Rademacher, A. Pontin, J. M. H. Gosling +2
Levitated optomechanics, the interaction between light and small levitated objects, is a new macroscopic quantum system that is being used as a testing ground for fundamental physi…
Feedback cooling scheme for an optically levitated oscillator with controlled cross-talk
J. M. H. Gosling, A. Pontin, F. Alder +3
Levitated optical mechanical systems have demonstrated excellent force and impulse sensitivity and are currently being developed for the creation of non-classical states of motion…
Optical centrifuge for nanoparticles
Peiyao Xiong, Kit Ka Kelvin Ho, J. M. H. Gosling +2
We study the creation of an optical centrifuge for the controlled rotation of levitated nanorotors within an optical tweezer. The optical centrifuge is created by rapidly rotating…
Sensing microscopic directional noise baths with an optically cooled and levitated nanoparticle
J. M. H. Gosling, A. Pontin, J. H. Iacoponi +2
Optomechanical devices are being harnessed as sensors of ultraweak forces for applications ranging from inertial sensing to the search for the elusive dark matter. For the latter,…
Simultaneous cooling of all six degrees of freedom of an optically levitated nanoparticle by elliptic coherent scattering
Antonio Pontin, Hayden Fu, Marko Toroš +2
We report on strong cooling and orientational control of all translational and angular degrees of freedom of a nanoparticle levitated in an optical trap in high vacuum. The motiona…
Characterisation of a charged particle levitated nano-oscillator
N. P. Bullier, A. Pontin, P. F. Barker
We describe the construction and characterisation of a nano-oscillator formed by a Paul trap. The frequency and temperature stability of the nano-oscillator was measured over sever…
