A Comprehensive Study on A Tapered Paul Trap: From Design to Potential Applications
Bo Deng, Moritz Göb, Max Masuhr +4
We present a tapered Paul trap whose radio frequency electrodes are inclined to the symmetric axis of the endcap electrodes, resulting in a funnel-shaped trapping potential. With t…
A single-atom heat engine
Johannes Roßnagel, Samuel Thomas Dawkins, Karl Nicolas Tolazzi +4
We report the experimental realization of a single-atom heat engine. An ion is confined in a linear Paul trap with tapered geometry and driven thermally by coupling it alternately…
A nano heat engine beyond the Carnot limit
Johannes Roßnagel, Obinna Abah, Ferdinand Schmidt-Kaler +2
Heat engines extract work by running cyclically between two heat reservoirs. When the two reservoirs are thermal and at different temperatures, the maximum efficiency of the engine…
Observation of the Kibble-Zurek scaling law for defect formation in ion crystals
S. Ulm, J. Roßnagel, G. Jacob +8
Traversal of a symmetry-breaking phase transition at a finite rate can lead to causallyseparated regions with incompatible symmetries and the formation of defects at their boundari…
Single ion heat engine with maximum efficiency at maximum power
Obinna Abah, Johannes Rossnagel, Georg Jacob +4
We propose an experimental scheme to realize a nano heat engine with a single ion. An Otto cycle may be implemented by confining the ion in a linear Paul trap with tapered geometry…
