Single-ion heat pump — •Dawid Crivelli1,2, Johannes Rossnagel1,2, Samuel Thomas Dawkins1,2, Ferdinand Schmidt-Kaler1, Georg Jacob1,2, and Kilian Singer1,2 — 1Quantum, Institut für Physik, Universität Mainz, D-55128 Mainz, Germany — 2Experimentalphysik I, Universität Kassel, Heinrich-Plett-Str. 40, D-34132 Kassel, Germany
We will present new concepts of implementing a heat pump with a single atom. Analytical and numerical predictions employing realistic experimental conditions are reviewed together with a new trap design for the implementation. We include a detailed description of the experimental procedure.
We build on the results of our previous implementation of a single ion heat engine [1,2,3], inverting the mechanism to realize a heat-pump, transferring heat from the cold to the hot reservoir, induced by an external electric field.
