Improved limits for violations of local position invariance from atomic clock comparisons
R. Lange, N. Huntemann, J. M. Rahm +6
We compare two optical clocks based on the SD electric quadrupole (E2) and the SF electric octupole (E3)…
Optical frequency ratio of a single-ion clock and a lattice clock
Sören Dörscher, Nils Huntemann, Roman Schwarz +6
We report direct measurements of the frequency ratio of the 642 THz -- electric octupole transition in and the 429 THz…
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…
Coherent suppression of tensor frequency shifts through magnetic field rotation
R. Lange, N. Huntemann, C. Sanner +4
We introduce a scheme to coherently suppress second-rank tensor frequency shifts in atomic clocks, relying on the continuous rotation of an external magnetic field during the free…
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…
Optical clock comparison test of Lorentz symmetry
Christian Sanner, Nils Huntemann, Richard Lange +4
Questioning the presumably most basic assumptions about the structure of space and time has revolutionized our understanding of Nature. State-of-the-art atomic clocks make it possi…
