A Cryogenic Penning Trap Based on Permanent Magnets
F. Völksen, K. K. Anjum, R. P. Czampiel +30
We report on a Penning trap based on NdFeB permanent magnets operated at 4\,K with a magnetic field strength of 280\,mT. Reliable loading and confinement of protons, H ions,…
Thorium-229 in its Highest Charge States: Single-Ion Nuclear Clocks for Tests of Fundamental Interactions
C. Brandau, P. Micke, I. Hartl +6
The prospects and the implementation of single-ion nuclear clocks of Th ions in their highest charge states are discussed. Highly-ionized-thorium…
The QTF-Backbone: Proposal for a Nationwide Optical Fibre Backbone in Germany for Quantum Technology and Time and Frequency Metrology
Tara Cubel Liebisch, Peter Kaufmann, Harald Schnatz +166
The recent breakthroughs in the distribution of quantum information and high-precision time and frequency (T&F) signals over long-haul optical fibre networks have transformative po…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
Orders of Magnitude Improved Cyclotron-Mode Cooling for Non-Destructive Spin Quantum Transition Spectroscopy with Single Trapped Antiprotons
B. M. Latacz, M. Fleck, J. I. Jaeger +21
We demonstrate efficient sub-thermal cooling of the modified cyclotron mode of a single trapped antiproton and reach particle temperatures below mK in p…
Image-current mediated sympathetic laser cooling of a single proton in a Penning trap down to 170 mK axial temperature
C. Will, M. Wiesinger, P. Micke +22
We demonstrate a new temperature record for image-current mediated sympathetic cooling of a single proton in a cryogenic Penning trap by laser-cooled Be. An axial mode temp…
