Electrostatic focusing of cold and heavy molecules for the ACME electron EDM search

Electrostatic focusing of cold and heavy molecules for the ACME electron EDM search

The current best upper limit for electron electric dipole moment (EDM), | d _e | < 1.1 × 10 ^−29 e cm (90% confidence), was set by the ACME Collaboration in 2018. The ACME experiment uses a spin-precession measurement in a cold beam of thorium monoxide (ThO) molecules to detect d _e . An improvem...
