Precision calculations of the hyperfine constants and isotope and isomer shifts in low-lying states of 229Th3+

S. G. Porsev, M. S. Safronova

We present high-precision calculations of the hyperfine constants, isotope shift, and isomer shift in low-lying states of Th3+ relevant to spectroscopy of the 229Th nuclear isomer.…

Shielded inner-shell transitions in atomic samarium for tests of fundamental physics

R. Aramyan, D. Budker, V. A. Dzuba +5

Forbidden atomic transitions provide some of the most stringent low-energy tests of physics beyond the Standard Model, with sensitivity set by the interplay between the sought-for…

A high-stability optical clock based on a continuously ground-state cooled Al ion without compromising its accuracy

Fabian Dawel, Lennart Pelzer, Kai Dietze +12

Single ion optical clocks have shown systematic frequency uncertainties below , but typically require more than one week of averaging to achieve a corresponding statistic…

Study of the elusive level crossing in highly charged osmium with optical transitions suitable for physics beyond the Standard Model searches

Nils-Holger Rehbehn, Lakshmi Priya Kozhiparambil Sajith, Michael K. Rosner +8

Optical transitions of highly charged ions can be very sensitive to hypothetical beyond-the-Standard-Model phenomena. Those near the level crossing, where the and …

Landé factor measurement of Ti using simultaneous co-magnetometry and quantum logic spectroscopy

Till Rehmert, Maximilian J. Zawierucha, Kai Dietze +6

The use of atomic systems as accurate magnetic field probes requires precise characterization of the particle's magnetic properties. Insufficient knowledge of the spatial and tempo…
