Systematic and statistical uncertainty evaluation of the HfF$^+$ electron electric dipole moment experiment

Atomic Physics 2023-07-12 v2

Abstract

We have completed a new precision measurement of the electron's electric dipole moment using trapped HfF+^+ in rotating bias fields. We report on the accuracy evaluation of this measurement, describing the mechanisms behind our systematic shifts. Our systematic uncertainty is reduced by a factor of 30 compared to the first generation of this measurement. Our combined statistical and systematic accuracy is improved by a factor of 2 relative to any previous measurement.
