High-accuracy multi-ion spectroscopy with mixed-species Coulomb crystals
J. Keller, H. N. Hausser, I. M. Richter +14
Multi-ion optical clocks offer the possibility of overcoming the low signal-to-noise ratio of single-ion clocks, while still providing low systematic uncertainties. We present simu…
Coherent excitation of the highly forbidden electric octupole transition in Yb
Henning A. Fürst, Chih-Han Yeh, Dimitri Kalincev +7
We report on the first coherent excitation of the highly forbidden electric octupole (E3) transition in a single trapped Yb ion, an…
Energy localization in interacting atomic chains with topological solitons
L. Timm, H. Weimer, L. Santos +1
Topological defects in low-dimensional non-linear systems feature a sliding-to-pinning transition of relevance for a variety of research fields, ranging from biophysics to nano- an…
Guidelines for developing optical clocks with fractional frequency uncertainty
Moustafa Abdel-Hafiz, Piotr Ablewski, Ali Al-Masoudi +42
There has been tremendous progress in the performance of optical frequency standards since the first proposals to carry out precision spectroscopy on trapped, single ions in the 19…
Towards a Transportable Aluminium Ion Quantum Logic Optical Clock
S. Hannig, L. Pelzer, N. Scharnhorst +7
With the advent of optical clocks featuring fractional frequency uncertainties on the order of and below, new applications such as chronometric levelling with few-cm hei…
Nanofriction and motion of topological defects in self-organized ion Coulomb crystals
Jan Kiethe, Ramil Nigmatullin, Thorben Schmirander +2
We study nanofriction in an ion Coulomb crystal under the presence of topological defects. We observe signatures of the pinning to sliding transition, namely the transverse vibrati…
