Measurement of single nanoparticle anisotropy by laser induced optical alignment and Rayleigh scattering for determining particle morphology
Markus Rademacher, Jonathan Gosling, Antonio Pontin +4
We demonstrate the measurement of nanoparticle shape by angularly resolved Rayleigh scattering of single optical levitated particles that are oriented in space via the trapping lig…
Towards directional force sensing in levitated optomechanics
A. Pontin, T. S. Monteiro
Levitated nanoparticles are being intensively investigated from two different perspectives: as a potential realisation of macroscopic quantum coherence; and as ultra-sensitive sens…
Controlling mode orientations and frequencies in levitated cavity optomechanics
A. Pontin, H. Fu, J. H. Iacoponi +2
Cavity optomechanics offers quantum cooling, quantum control and measurement of small mechanical oscillators. However the optical backactions that underpin quantum control can sign…
Imaging based feedback cooling of a levitated nanoparticle
Yosuke Minowa, Keisuke Kato, Shoki Ueno +4
Imaging-based detection of the motion of the levitated nanoparticles complements a widely-used interferometric detection method, providing a precise and robust way to estimate the…
Cavity optomechanics in a fiber cavity: the role of stimulated Brillouin scattering
Abel Beregi, Peter F. Barker, Antonio Pontin
We study the role of stimulated Brillouin scattering in a fiber cavity by numerical simulations and a simple theoretical model and find good agreement between experiment, simulatio…
