On the potential for high-accuracy spectroscopy of and in Penning traps for a test of CPT invariance
Stephan Schiller, Juan M. Cornejo, Nikita Poljakov +3
The comparison of vibrational transition frequencies of and offers a new opportunity to test CPT invariance. Myers [Phys. Rev. A 98, 01…
A robust method to reach the motional quantum regime of (anti-)protons in cryogenic multi-Penning traps
Nikita Poljakov, Jan Schaper, Julia-Aileen Coenders +5
Sympathetic laser cooling is a key concept in precision spectroscopy and quantum state control of charged particles. Significant challenges arise in the metrologically relevant cas…
Full Single-Quantum Control of Particles in Penning Traps for Symmetry Tests at the Quantum Limit
J. M. Cornejo, J. -A. Coenders, A. Lissel +9
The BASE collaboration aims to measure antimatter systems with the highest precision in order to perform a rigorous test of CPT symmetry and search for physics beyond the Standard…
