Description:
Control over the motional degrees of freedom of atoms, ions, and molecules in a field-free environment enables unrivalled measurement accuracies but has yet to be applied to highly charged ions (HCIs), which are of particular interest to future atomic clock designs and searches for physics beyond the Standard Model. Here, we report on the Coulomb crystallization of HCIs (specifically (40)Ar(13+)) produced in an electron beam ion trap and retrapped in a cryogenic linear radiofrequency trap by means of sympathetic motional cooling through Coulomb interaction with a directly laser-cooled ensemble of Be(+) ions. We also demonstrate cooling of a single Ar(13+) ion by a single Be(+) ion-the prerequisite for quantum logic spectroscopy with a potential 10(-19) accuracy level. Achieving a seven-orders-of-magnitude decrease in HCI temperature starting at megakelvin down to the millikelvin range removes the major obstacle for HCI investigation with high-precision laser spectroscopy.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Schmoger, L -- Versolato, O O -- Schwarz, M -- Kohnen, M -- Windberger, A -- Piest, B -- Feuchtenbeiner, S -- Pedregosa-Gutierrez, J -- Leopold, T -- Micke, P -- Hansen, A K -- Baumann, T M -- Drewsen, M -- Ullrich, J -- Schmidt, P O -- Lopez-Urrutia, J R Crespo -- New York, N.Y. -- Science. 2015 Mar 13;347(6227):1233-6. doi: 10.1126/science.aaa2960.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Max-Planck-Institut fur Kernphysik, Saupfercheckweg 1, 69117 Heidelberg, Germany.
