  Recent improvements in experimental techniques for preparing ultracold
molecules that contain alkali atoms (e.g., Li, Na, and K) have been reported.
Based on these advances in ultracold molecules, new searches for the electric
dipole moment of the electron and the scalar-pseudoscalar interaction can be
proposed on such systems. We calculate the effective electric fields (Eeff) and
the S-PS coefficients (Ws) of SrA and HgA (A = Li, Na, and K) molecules at the
Dirac-Fock (DF) and the relativistic coupled cluster (RCC) levels. We elaborate
on the following points: i) Basis set dependence of the molecular properties in
HgA, ii) Analysis of Eeff and Ws in SrA and HgA, and comparison with their
fluoride and hydride counterparts, iii) Ratio of Ws to Eeff (Ws/Eeff) at the DF
and the correlation RCC levels of theory.
