Heterodyne position detection of an optomechanical system
Daniel Tandeitnik, Gabriel Dias, Thiago Guerreiro
We report a heterodyne detection scheme for position readout of an optomechanical system, in particular an optically levitated particle, implemented via digital In-phase and Quadra…
All electrical cooling of an optically levitated nanoparticle
Oscar Kremer, Igor Califrer, Daniel Tandeitnik +3
We implement an all electrical controller for 3D feedback cooling of an optically levitated nanoparticle capable of reaching sub-Kelvin temperatures for the center of mass motion.…
Generation of classical non-Gaussian distributions by squeezing a thermal state into non-linear motion of levitated optomechanics
Rafael Muffato, Tiberius Georgescu, Jack Homans +6
We report on an experiment achieving the dynamical generation of non-Gaussian states of motion of a levitated optomechanical system. We access intrinsic Duffing-like nonlinearities…
Perturbative nonlinear feedback forces for optical levitation experiments
Oscar Kremer, Daniel Tandeitnik, Rafael Mufato +6
Feedback control can be used to generate well-determined nonlinear effective potentials in an optical trap, a goal whose applications may range from non-equilibrium thermodynamics…
