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…
Generalized excitation of atomic multipole transitions by twisted light modes
S. A. -L. Schulz, A. A. Peshkov, R. A. Müller +5
A theoretical study is performed for the excitation of a single atom localized in the center of twisted light modes. Here we present the explicit dependence of excitation rates on…
Search for transient variations of the fine structure constant and dark matter using fiber-linked optical atomic clocks
B. M. Roberts, P. Delva, A. Al-Masoudi +51
We search for transient variations of the fine structure constant using data from a European network of fiber-linked optical atomic clocks. By searching for coherent variations in…
