Unexpectedly large difference of the electron density at the nucleus in the 4p P fine-structure doublet of Ca
C. Shi, F. Gebert, C. Gorges +9
We measured the isotope shift in the S-P (D2) transition in singly-ionized calcium ions using photon recoil spectroscopy. The high accuracy of the technique…
Detection of motional ground state population of a trapped ion using delayed pulses
Florian Gebert, Yong Wan, Fabian Wolf +2
Efficient preparation and detection of the motional state of trapped ions is important in many experiments ranging from quantum computation to precision spectroscopy. We investigat…
Non-destructive state detection for quantum logic spectroscopy of molecular ions
Fabian Wolf, Yong Wan, Jan C. Heip +3
Laser spectroscopy of cold and trapped molecular ions is a powerful tool for fundamental physics, including the determination of fundamental constants, the laboratory test for thei…
Precision isotope shift measurements in Ca using highly sensitive detection schemes
Florian Gebert, Yong Wan, Fabian Wolf +3
We demonstrate an efficient high-precision optical spectroscopy technique for single trapped ions with non-closed transitions. In a double-shelving technique, the absorption of a s…
Efficient sympathetic motional ground-state cooling of a molecular ion
Yong Wan, Florian Gebert, Fabian Wolf +1
Cold molecular ions are promising candidates in various fields ranging from precision spectroscopy and test of fundamental physics to ultra-cold chemistry. Control of internal and…
Precision spectroscopy by photon-recoil signal amplification
Yong Wan, Florian Gebert, Jannes B. Wübbena +7
Precision spectroscopy of atomic and molecular ions offers a window to new physics, but is typically limited to species with a cycling transition for laser cooling and detection. Q…
A Single Laser System for Ground-State Cooling of 25-Mg+
Boerge Hemmerling, Florian Gebert, Yong Wan +3
We present a single solid-state laser system to cool, coherently manipulate and detect Mg ions. Coherent manipulation is accomplished by coupling two hyperfine ground st…
