In search of suitable molecular candidates for probing the electric dipole moment (EDM) electron (de), a property that arises due to parity and time-reversal violating (P,T-odd) interactions, we consider triatomic mercury hydroxide (HgOH) molecule. The impetus this proposal is based on previous works two systems: recently proposed ytterbium (YbOH) experiment demonstrates advantages polyatomics such EDM searches, finding halides provide highest enhancement de compared other diatomic...

We analyze the electric dipole moments and static polarizabilities of alkali-metal--alkaline-earth-metal (Alk-AlkE) dimers by employing finite-field coupled-cluster methods in frameworks both nonrelativistic four-component spin-free relativistic theories. In order to carry out comparative analyses rigorously, we consider those Alk-AlkE molecules made lightest medium-heavy constituent atoms (Alk: Li Rb AlkE: Be through Sr). present behavior electron correlation effects as well related size...

We analyze the molecular electric dipole moments (PDMs) and static polarizabilities of heteronuclear alkali dimers in their ground states by employing coupled-cluster theory, both non-relativistic four-component relativistic frameworks. The roles electron correlations as well effects are demonstrated studying them at different levels followed a comprehensive treatment error estimates. compare our obtained values with previous calculations, some which include lower-order corrections,...

Molecules containing superheavy atoms can be artificially created to serve as sensitive probes study symmetry-violating phenomena. Here, we provide detailed theoretical studies of quantities relevant the electron electric dipole moment (eEDM) and nucleus-electron scalar-pseudoscalar interactions in diatomic molecules lawrencium nuclei. The sensitivity parity time (or, equivalently, CP) reversal violating properties is studied for different neutral ionic molecules. effective fields these...

In the quest to find a favourable triatomic molecule for detecting electric dipole moment of an electron (eEDM), we identify mercury hydroxide (HgOH) as extremely attractive candidate from both experimental and theoretical viewpoints. Our calculations show that there is four-fold enhancement in effective field HgOH compared recently proposed ytterbium (YbOH) [Phys. Rev. Lett. 119, 133002 (2017)] eEDM measurement. Thus, (010) bending state associated with electronic ground state, it could...

In view of the large differences in previous calculations enhancement factors to parity and time-reversal violating (P,T-odd) electric dipole moment (EDM) $^{225}$Ra due nuclear Schiff (NSM) tensor-pseudotensor (T-PT) electron-nucleus (e-N) interactions between relativistic coupled-cluster (RCC) theory other many-body methods, we employ normal (RNCC) explain discrepancies. The normalization wave function RNCC becomes unity by construction. This feature removes ambiguity associated with...
