Sympathetic cooling schemes for separately trapped ions coupled via image currents
C. Will, M. Bohman, T. Driscoll +18
Cooling of particles to mK-temperatures is essential for a variety of experiments with trapped charged particles. However, many species of interest lack suitable electronic transit…
Sympathetic cooling of a trapped proton mediated by an LC circuit
M. Bohman, V. Grunhofer, C. Smorra +18
Efficient cooling of trapped charged particles is essential to many fundamental physics experiments, to high-precision metrology, and to quantum technology. Until now, sympathetic…
Towards Sympathetic Cooling of Single (Anti-)Protons
T. Meiners, M. Niemann, J. Mielke +5
We present methods to manipulate and detect the motional state and the spin state of a single antiproton or proton which are currently under development within the BASE (Baryon Ant…
Cryogenic Penning-Trap Apparatus for Precision Experiments with Sympathetically Cooled (anti)protons
M. Niemann, T. Meiners, J. Mielke +17
Current precision experiments with single (anti)protons to test CPT symmetry progress at a rapid pace, but are complicated by the need to cool particles to sub-thermal energies. We…
139 GHz UV phase-locked Raman laser system for thermometry and sideband cooling of Be ions in a Penning trap
Johannes Mielke, Julian Pick, Julia A. Coenders +5
We demonstrate phase locking of two ultraviolet laser sources by modulating a fundamental infrared laser with 4th-order sidebands using an electro-optic modulator and phase locking…
