Entropy production and non-Gaussianity of fast processes at weak damping
Mario A. Ciampini, Jakob Rieser, Nikolai Kiesel +1
We present a method of estimating the rate of entropy production in underdamped dynamics by decomposing it into contributions originating in different non-equilibrium effects. Spec…
Feedback stabilization of a nanoparticle at the intensity minimum of an optical double-well potential
Vojtěch Mlynář, Salambô Dago, Jakob Rieser +5
In this work, we develop and analyze adaptive feedback control strategies to stabilize and confine a nanoparticle at the unstable intensity minimum of an optical double-well potent…
Stabilizing nanoparticles in the intensity minimum: feedback levitation on an inverted potential
Salambô Dago, Jakob Rieser, Mario A. Ciampini +5
We demonstrate the stable trapping of a levitated nanoparticle on top of an inverted potential using a combination of optical readout and electrostatic control. The feedback levita…
Hollow-core fiber loading of nanoparticles into ultra-high vacuum
Stefan Lindner, Paul Juschitz, Jakob Rieser +4
Many experiments in the field of optical levitation with nanoparticles today are limited by the available technologies for particle loading. Here we introduce a new particle loadin…
