RF-induced heating dynamics of non-crystallized trapped ions
Martin W. van Mourik, Pavel Hrmo, Lukas Gerster +4
We investigate the energy dynamics of non-crystallized (melted) ions, confined in a Paul trap. The non-periodic Coulomb interaction experienced by melted ions forms a medium for no…
Faraday rotation of a tightly focussed beam from a single trapped atom
G. Hétet, L. Slodička, N. Röck +1
Faraday rotation of a laser field induced by a single atom is demonstrated by tightly focussing a linearly polarized laser beam onto a laser-cooled ion held in a harmonic Paul trap…
Compact RF resonator for cryogenic ion traps
D. Gandolfi, M. Niedermayr, M. Kumph +2
We report on the investigation and implementation of a lumped-component, radio-frequency resonator used in a cryogenic vacuum environment to drive an ion trap. The resonator was re…
Precision measurement of the branching fractions of the 4P3/2 decay of Ca II
R. Gerritsma, G. Kirchmair, F. Zaehringer +3
We perform precision measurements of the branching ratios of the 4P3/2 level decay of a single 40Ca+ ion suspended in a linear Paul trap. High precision is achieved by a novel tech…
Absolute frequency measurement of the 40Ca+ S1/2 - D5/2 clock transition
M. Chwalla, J. Benhelm, K. Kim +12
We report on the first absolute transition frequency measurement at the 10^{-15} level with a single, laser-cooled 40Ca+ ion in a linear Paul trap. For this measurement, a frequenc…
