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.…

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…
