Attaining the shot-noise-limit in the ACME measurement of the electron electric dipole moment

Experimental searches for the electron electric dipole moment, d_e, probe new physics beyond the Standard Model. Recently, the ACME Collaboration set a new limit of |d_e| <1.1\times 10^{-29} e\cdot \textrm{cm} [Nature \textbf{562}, 355 (2018)], constraining time reversal symmetry (T) violating physics in the 3-100 TeV energy scale. ACME extracts d_e... Show more
