Experimental Constraint on Axionlike Particles over Seven Orders of Magnitude in Mass Open
We use our recent electric dipole moment (EDM) measurement data to constrain the possibility that the HfF^{+} EDM oscillates in time due to interactions with candidate dark matter axionlike particles (ALPs). We employ a Bayesian analysis m…

The First Precision Measurement of the Electron Electric Dipole Moment in Trapped Molecular Ions Open
A measurement of the permanent electric dipole moment of the electron (eEDM, de) is a direct probe of physics beyond the Standard Model. Our experiment makes a measurement of the eEDM in Hafnium Fluoride ions (HfF+) using a novel radiofreq…

Precision Measurement of the Electron’s Electric Dipole Moment Using Trapped Molecular Ions Open
We describe the first precision measurement of the electron's electric dipole moment (d_{e}) using trapped molecular ions, demonstrating the application of spin interrogation times over 700 ms to achieve high sensitivity and stringent reje…
