Long-distance chronometric leveling with a portable optical clock
J. Grotti, I. Nosske, S. B. Koller +19
We have measured the geopotential difference between two locations separated by by comparison of two optical lattice clocks via an interferometric fiber link, uti…
The helion charge radius from laser spectroscopy of muonic helium-3 ions
The CREMA Collaboration, Karsten Schuhmann, Luis M. P. Fernandes +37
Hydrogen-like light muonic ions, in which one negative muon replaces all the electrons, are extremely sensitive probes of nuclear structure, because the large muon mass increases t…
Number-Resolved Detection of Dark Ions in Coulomb Crystals
Fabian Schmid, Johannes Weitenberg, Jorge Moreno +3
While it is straightforward to count laser-cooled trapped ions by fluorescence imaging, detecting the number of dark ions embedded and sympathetically cooled in a mixed ion crystal…
Motional resonances of three-dimensional dual-species Coulomb crystals
Byoung-moo Ann, Fabian Schmid, Jonas Krause +3
We investigate the motional resonances of dual-species Coulomb crystals comprised of Be and Mg ions held in a 4-rod linear Paul trap. Our experimental data and s…
The proton radius puzzle
J. J. Krauth, K. Schuhmann, M. Abdou Ahmed +49
High-precision measurements of the proton radius from laser spectroscopy of muonic hydrogen demonstrated up to six standard deviations smaller values than obtained from electron-pr…
Deuteron charge radius and Rydberg constant from spectroscopy data in atomic deuterium
Randolf Pohl, François Nez, Thomas Udem +11
We give a pedagogical description of the method to extract the charge radii and Rydberg constant from laser spectroscopy in regular hydrogen (H) and deuterium (D) atoms, that is pa…
