Direct limits on the interaction of antiprotons with axion-like dark matter
C. Smorra, Y. V. Stadnik, P. E. Blessing +18
Astrophysical observations indicate that there is roughly five times more dark matter in the Universe than ordinary baryonic matter, with an even larger amount of the Universe's en…
Cryogenic Be Penning trap for precision measurements with (anti-)protons
Malte Niemann, Teresa Meiners, Johannes Mielke +4
Cooling and detection schemes using laser cooling and methods of quantum logic can contribute to high precision CPT symmetry tests in the baryonic sector. This work introduces an e…
Measurement of ultra-low heating rates of a single antiproton in a cryogenic Penning trap
M. J. Borchert, P. E. Blessing, J. A. Devlin +15
We report on the first detailed study of motional heating in a cryogenic Penning trap using a single antiproton. Employing the continuous Stern-Gerlach effect we observe cyclotron…
Observation of individual spin quantum transitions of a single antiproton
C. Smorra, A. Mooser, M. Besirli +15
We report on the detection of individual spin quantum transitions of a single trapped antiproton in a Penning trap. The spin-state determination, which is based on the unambiguous…
