Nonequilibrium thermodynamics and optimal cooling of a dilute atomic gas
Daniel Mayer, Felix Schmidt, Steve Haupt +5
Characterizing and optimizing thermodynamic processes far from equilibrium is a challenge. This is especially true for nanoscopic systems made of few particles. We here theoretical…
Tailored single-atom collisions at ultra-low energies
Felix Schmidt, Daniel Mayer, Quentin Bouton +5
We employ collisions of individual atomic cesium (Cs) impurities with an ultracold rubidium (Rb) gas to probe atomic interaction with hyperfine- and Zeeman-state sensitivity. Contr…
Controlled doping of a bosonic quantum gas with single neutral atoms
Daniel Mayer, Felix Schmidt, Daniel Adam +6
We report on the experimental doping of a Rubidium (Rb) Bose-Einstein condensate (BEC) with individual neutral Cesium (Cs) atoms. We discuss the experimental tools a…
Quantum spin dynamics of individual neutral impurities coupled to a Bose-Einstein condensate
Felix Schmidt, Daniel Mayer, Quentin Bouton +4
We report on spin dynamics of individual, localized neutral impurities immersed in a Bose-Einstein condensate. Single Cesium atoms are transported into a cloud of Rubidium atoms, t…
Optimizing Quantum Gas Production by an Evolutionary Algorithm
Tobias Lausch, Michael Hohmann, Farina Kindermann +3
We report on the application of an evolutionary algorithm (EA) to enhance performance of an ultra-cold quantum gas experiment. The production of a Rubidium Bose-Einstein con…
Neutral Impurities in a Bose-Einstein Condensate for Simulation of the Fröhlich-Polaron
Michael Hohmann, Farina Kindermann, Benjamin Gänger +4
We present an experimental system to study the Bose polaron by immersion of single, well-controllable neutral Cs impurities into a Rb Bose-Einstein condensate (BEC). We show that,…
