A 16 Parts per Trillion Comparison of the Antiproton-to-Proton q/m Ratios
M. J. Borchert, J. A. Devlin, S. E. Erlewein +20
The Standard Model (SM) of particle physics is both incredibly successful and glaringly incomplete. Among the questions left open is the striking imbalance of matter and antimatter…
Resolved-sideband cooling of a single Be ion in a Penning trap
Juan M. Cornejo, Johannes Brombacher, Julia A. Coenders +5
Manipulating individual trapped ions at the single quantum level has become standard practice in radio-frequency ion traps, enabling applications from quantum information processin…
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…
Fast adiabatic transport of single laser-cooled Be ions in a cryogenic Penning trap stack
T. Meiners, J. -A. Coenders, J. Mielke +4
High precision mass and -factor measurements in Penning traps have enabled groundbreaking tests of fundamental physics. The most advanced setups use multi-trap methods, which em…
Optical stimulated-Raman sideband spectroscopy of a single Be ion in a Penning trap
J. M. Cornejo, J. Brombacher, J. -A. Coenders +5
We demonstrate optical sideband spectroscopy of a single Be ion in a cryogenic 5 Tesla Penning trap using two-photon stimulated-Raman transitions between the two Zeeman sub…
