Cold highly charged ions in a radio-frequency trap with superconducting magnetic shielding
Elwin A. Dijck, Christian Warnecke, Malte Wehrheim +12
We implement sympathetic cooling of highly charged ions (HCI) by fully enclosing a linear Paul trap within a superconducting radio-frequency resonator. A quantization magnetic fiel…
Sensitivity to New Physics of Isotope Shift Studies using the Coronal Lines of Highly Charged Calcium Ions
Nils-Holger Rehbehn, Michael K. Rosner, Hendrik Bekker +8
Promising searches for new physics beyond the current Standard Model (SM) of particle physics are feasible through isotope-shift spectroscopy, which is sensitive to a hypothetical…
Algorithmic Ground-state Cooling of Weakly-Coupled Oscillators using Quantum Logic
Steven A. King, Lukas J. Spieß, Peter Micke +4
Most ions lack the fast, cycling transitions that are necessary for direct laser cooling. In most cases, they can still be cooled sympathetically through their Coulomb interaction…
An ultralow-noise superconducting radio-frequency ion trap for frequency metrology with highly charged ions
J. Stark, C. Warnecke, S. Bogen +17
We present a novel ultrastable superconducting radio-frequency (RF) ion trap realized as a combination of an RF cavity and a linear Paul trap. Its RF quadrupole mode at 34.52 MHz r…
The Heidelberg compact electron beam ion traps
P. Micke, S. Kühn, L. Buchauer +16
Electron beam ion traps (EBIT) are ideal tools for both production and study of highly charged ions (HCI). In order to reduce their construction, maintenance, and operation costs w…
Coherent laser spectroscopy of highly charged ions using quantum logic
P. Micke, T. Leopold, S. A. King +6
Precision spectroscopy of atomic systems is an invaluable tool for the advancement of our understanding of fundamental interactions and symmetries. Recently, highly charged ions (H…
