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…
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…
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…
