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…
Excited-state magnetic properties of carbon-like
Lukas J. SpieÃ, Shuying Chen, Alexander Wilzewski +13
We measured the -factor of the excited state in ion to be with a relative uncertainty of . The magnetic field…
Finding the ultra-narrow electric quadrupole transition in Ni ion for an optical clock
Charles Cheung, Sergey G. Porsev, Dmytro Filin +7
The Ni ion features an electronic transition with a natural width of only 8 mHz, allowing for a highly stable optical clock. We predict that the energy of this strongly for…
A neural network approach to running high-precision atomic computations
Pavlo Bilous, Charles Cheung, Marianna Safronova
Modern applications of atomic physics, including the determination of frequency standards, and the analysis of astrophysical spectra, require prediction of atomic properties with e…
Natural-linewidth measurements of the 3C and 3D soft-x-ray transitions in Ni XIX
Chintan Shah, Steffen Kühn, Sonja Bernitt +15
We used the monochromatic soft-x-ray beamline P04 at the synchrotron-radiation facility PETRA III to resonantly excite the strongest transitions in neon-like Ni XIX ions, $…
