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…

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…
