Probing the spatial distribution of k-vectors in situ with Bose-Einstein condensates
Samuel Gaudout, Rayan Si-Ahmed, Clément Debavelaere +3
We present a novel method for mapping \textit{in situ} the spatial distribution of photon momentum across a laser beam using a Bose-Einstein condensate (BEC) as a moving probe. By…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
Probing new bosons and nuclear structure with ytterbium isotope shifts
Menno Door, Chih-Han Yeh, Matthias Heinz +24
In this Letter, we present mass-ratio measurements on highly charged Yb ions with a precision of and isotope-shift measurements on Yb on the …
Atomic mass determination of uranium-238
Kathrin Kromer, Chunhai Lyu, Jacek Bieroń +10
The atomic mass of uranium-238 has been determined to be , improving the literature uncertainty by two orders of magnitude. It is obtained from a m…
Observation of a low-lying metastable electronic state in highly charged lead by Penning-trap mass spectrometry
Kathrin Kromer, Chunhai Lyu, Menno Door +10
Highly charged ions (HCIs) offer many opportunities for next-generation clock research due to the vast landscape of available electronic transitions in different charge states. The…
High-precision determination of factors and masses of and
F. Heiße, M. Door, T. Sailer +13
We present the measurements of individual bound electron factors of and on the relative level of per billion. Th…
A Digital Feedback System for Advanced Ion Manipulation Techniques in Penning Traps
Jost Herkenhoff, Menno Door, Pavel Filianin +7
The possibility to apply active feedback to a single ion in a Penning trap using a fully digital system is demonstrated. Previously realized feedback systems rely on analog circuit…
Detection of metastable electronic states by Penning trap mass spectrometry
Rima Xenia Schüssler, Hendrik Bekker, Martin Braß +19
State-of-the-art optical clocks achieve fractional precisions of and below using ensembles of atoms in optical lattices or individual ions in radio-frequency traps. Prom…
Production of highly charged ions of rare species by laser-induced desorption inside an electron beam ion trap
Christoph Schweiger, Charlotte König, José R. Crespo López-Urrutia +13
This paper reports on the development and testing of a novel, highly efficient technique for the injection of very rare species into electron beam ion traps (EBITs) for the product…
