Precision spectroscopy in Yb+ ions
Jialiang Yu, Kai C. Grensemann, Chih-Han Yeh +5
We report on our progress on multi-ion spectroscopy with Yb+ ions. We first characterized the spatial homogeneity of the magnetic- and the rf-field. Subsequently, to equalize the i…

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 …

Improved bounds on Lorentz violation from composite-pulse Ramsey spectroscopy in a trapped ion
Laura S. Dreissen, Chih-Han Yeh, Henning A. Fürst +2
In attempts to unify the four known fundamental forces in a single quantum-consistent theory, it is suggested that Lorentz symmetry may be broken at the Planck scale. Here we searc…
