Lifetime of the level in Yb for spontaneous emission of electric octupole radiation
R. Lange, A. A. Peshkov, N. Huntemann +3
We report a measurement of the radiative lifetime of the level of Yb that is coupled to the ground state via an electric octupole transition. Th…
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)…
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…
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…
