Experimental verification of a reversed Clausius inequality in an isolated system
Daniel Mayer, Eric Lutz, Artur Widera
The second law of thermodynamics is a fundamental law of Nature. It is almost universally associated with the Clausius inequality that lower bounds a change in entropy by the ratio…
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…
