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…
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…
