Prospects for a polar-molecular-ion optical probe of varying proton-electron mass ratio
Prospects for a polar-molecular-ion optical probe of varying proton-electron mass ratio
Molecules with deep vibrational potential wells provide optical intervals sensitive to variation in the proton-electron mass ratio ($\ensuremath{\mu}$). On one hand, polar molecules are of interest since optical state preparation techniques have been demonstrated for such species. On the other hand, it might be assumed that polar species are unfavorable …
