معرفی
C. Ospelkaus is a researcher at GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, specializing in high-precision measurements of fundamental particle properties. As part of the international BASE collaboration, they conduct cutting-edge research on antiprotons and protons using advanced Penning trap techniques.
Their research focuses on testing fundamental symmetries of nature, particularly CPT symmetry, through ultra-precise comparisons of proton and antiproton properties. Recent work has achieved measurements at the parts-per-trillion level, representing some of the most precise tests of fundamental physics principles.
Key research areas include:
- Antimatter research and precision spectroscopy
- Development of advanced Penning trap techniques
- Sympathetic cooling methods for single particles
- Quantum state manipulation and measurement
- Transportable antimatter storage systems
Publications over the past five years show consistent high-impact contributions to fundamental physics, with articles appearing in Nature and Physical Review Letters. The research demonstrates steady progress toward ever-higher precision in fundamental particle measurements.
Notable achievements include:
- 16-parts-per-trillion measurement of antiproton-to-proton charge-mass ratio (2022)
- Development of BASE-STEP transportable antiproton reservoir (2023)
- Orders of magnitude improved cyclotron-mode cooling techniques (2024)
- Coherent spectroscopy with single antiproton spins (2025)
This research provides critical tests of fundamental symmetries in physics, with potential implications for understanding matter-antimatter asymmetry in the universe and searching for physics beyond the Standard Model.
