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 …
Robust and scalable rf spectroscopy in first-order magnetic sensitive states at second-long coherence time
C. -H. Yeh, K. C. Grensemann, L. S. Dreissen +2
Trapped-ion quantum sensors have become highly sensitive tools for the search of physics beyond the Standard Model. Recently, stringent tests of local Lorentz-invariance (LLI) have…
Systematic study of tunable laser cooling for trapped-ion experiments
A. P. Kulosa, O. N. Prudnikov, D. Vadlejch +5
We report on a comparative analysis of quenched sideband cooling in trapped ions. We introduce a theoretical approach for time-efficient simulation of the temporal cooling characte…
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…
Buffer gas cooling of ions in time-dependent traps using ultracold atoms
E. Trimby, H. Hirzler, H. Fürst +3
For exploration of quantum effects with hybrid atom-ion systems, reaching ultracold temperatures is the major limiting factor. In this work, we present results on numerical simulat…
Trapped ions in Rydberg-dressed atomic gases
T. Secker, N. Ewald, J. Joger +3
We theoretically study trapped ions that are immersed in an ultracold gas of Rydberg-dressed atoms. By off-resonant coupling on a dipole-forbidden transition, the adiabatic atom-io…
