Levitated Optomechanics with Meta-Atoms
Sergei Lepeshov, Nadine Meyer, Patrick Maurer +2
We propose to introduce additional control in levitated optomechanics by trapping a meta-atom, i.e. a subwavelength and high-permittivity dielectric particle supporting Mie resonan…
Optomechanical sideband asymmetry explained by stochastic electrodynamics
Lukas Novotny, Martin Frimmer, Andrei Militaru +3
Within the framework of stochastic electrodynamics we derive the noise spectrum of a laser beam reflected from a suspended mirror. The electromagnetic field follows Maxwell's equat…
Interaction Between an Optically Levitated Nanoparticle and Its Thermal Image: Internal Thermometry via Displacement Sensing
Thomas Agrenius, Carlos Gonzalez-Ballestero, Patrick Maurer +1
We propose and theoretically analyze an experiment where displacement sensing of an optically levitated nanoparticle in front of a surface can be used to measure the induced dipole…
Suppressing Recoil Heating in Levitated Optomechanics using Squeezed Light
C. Gonzalez-Ballestero, J. A. Zielińska, M. Rossi +5
We theoretically show that laser recoil heating in free-space levitated optomechanics can be arbitrarily suppressed by shining squeezed light onto an optically trapped nanoparticle…
Preparation of Metrological States in Dipolar-Interacting Spin Systems
Tian-Xing Zheng, Anran Li, Jude Rosen +7
Spin systems are an attractive candidate for quantum-enhanced metrology. Here we develop a variational method to generate metrological states in small dipolar-interacting ensembles…
