On the potential for high-accuracy spectroscopy of $H_{2}^{+}$ and $H_{2}^{-}$ in Penning traps for a test of CPT invariance

Stephan Schiller, Juan M. Cornejo, Nikita Poljakov +3

The comparison of vibrational transition frequencies of $H_{2}^{+}$ and $H_{2}^{-}$ 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…
