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…
Buffer gas cooling of a trapped ion to the quantum regime
T. Feldker, H. Fürst, H. Hirzler +5
Great advances in precision quantum measurement have been achieved with trapped ions and atomic gases at the lowest possible temperatures. These successes have inspired ideas to me…
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…
Controlling the transport of an ion: Classical and quantum mechanical solutions
H. A. Fürst, M. H. Goerz, U. G. Poschinger +6
We investigate the performance of different control techniques for ion transport in state-of-the-art segmented miniaturized ion traps. We employ numerical optimization of classical…
