Finite temperature spectrum at the symmetry-breaking linear-zigzag transition
Jan Kiethe, Lars Timm, Haggai Landa +3
We investigate the normal mode spectrum of a trapped ion chain at the symmetry-breaking linear to zigzag transition and at finite temperatures. For this purpose we modulate the amp…
Motional heating of spatially extended ion crystals
D. Kalincev, L. S. Dreissen, A. P. Kulosa +3
We study heating of motional modes of a single ion and of extended ion crystals trapped in a linear radio frequency (rf) Paul trap with a precision of …
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…
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…
Controlling systematic frequency uncertainties at the level in linear Coulomb crystals
J. Keller, T. Burgermeister, D. Kalincev +5
Trapped ions are ideally suited for precision spectroscopy, as is evident from the remarkably low systematic uncertainties of single-ion clocks. The major weakness of these clocks…
Probing Time Dilation in Coulomb Crystals in a high-precision Ion Trap
J. Keller, D. Kalincev, T. Burgermeister +5
Trapped-ion optical clocks are capable of achieving systematic fractional frequency uncertainties of and possibly below. However, the stability of current ion clocks is…
Probing Nanofriction and Aubry-type signatures in a finite self-organized system
Jan Kiethe, Ramil Nigmatullin, Dimitri Kalincev +2
Friction in ordered atomistic layers plays a central role in various nanoscale systems ranging from nanomachines to biological systems. It governs transport properties, wear and di…
Evaluation of trap-induced systematic frequency shifts for a multi-ion optical clock at the level
J. Keller, T. Burgermeister, D. Kalincev +2
In order to improve the short-term stability of trapped-ion optical clocks, we are developing a frequency standard based on In / Yb Coulomb crystals…
