STIRAP preparation of a coherent superposition of ThO H^3Δ_1 states for an improved electron EDM measurement

Experimental searches for the electron electric dipole moment (EDM) probe new physics beyond the Standard Model. The current best EDM limit was set by the ACME Collaboration [Science \textbf{343}, 269 (2014)], constraining time reversal symmetry (T) violating physics at the TeV energy scale. ACME used optical pumping to prepare a... Show more
