A new bound on the electron's electric dipole moment

ORAL · Invited

Abstract

We will present the most precise measurement of the electron’s electric dipole moment using electron

spin spectroscopy with up to 3 s coherence time for molecular ions confined in an ion trap. Our result is

consistent with zero and improves on the previous best upper bound [1] by a factor ∼ 2.4 [2].
