Determination of a set of fundamental constants from molecular hydrogen ion spectroscopy: a modeling study
J. -Ph Karr, S. Schiller, V. I. Korobov +1
The rovibrational transition frequencies of molecular hydrogen ions (MHI) can be accurately computed using ab initio nonrelativistic quantum electrodynamics. A subset of the fundam…

Proton-electron mass ratio by high-resolution optical spectroscopy of ion ensembles in the resolved-carrier regime
I. V. Kortunov, S. Alighanbari, M. G. Hansen +3
Optical spectroscopy in the gas phase is a key tool to elucidate the structure of atoms and molecules and of their interaction with external fields. The line resolution is usually…

Rotational spectroscopy of cold, trapped molecular ions in the Lamb-Dicke regime
Soroosh Alighanbari, Michael Georg Hansen, Vladimir Korobov +1
Sympathetic cooling of trapped ions has been established as a powerful technique for manipulation of non-laser-coolable ions (Raizen1992,Waki1992,Bowe1999,Barrett2003). For molecul…
