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…
Implications of surface noise for the motional coherence of trapped ions
I. Talukdar, D. J. Gorman, N. Daniilidis +5
Electric noise from metallic surfaces is a major obstacle towards quantum applications with trapped ions due to motional heating of the ions. Here, we discuss how the same noise so…
Interferometric thermometry of a single sub-Doppler cooled atom
L. Slodička, G. Hétet, N. Röck +5
Efficient self-interference of single-photons emitted by a sideband-cooled Barium ion is demonstrated. First, the technical tools for performing efficient coupling to the quadrupol…
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…
