A Relativistic Many-Body Analysis of the Electric Dipole Moment of Rn
B. K. Sahoo, Yashpal Singh, B. P. Das
We report the results of our {\it ab initio} relativistic many-body calculations of the electric dipole moment (EDM) arising from the electron-nucleus tensor-pseudotensor (T-…
Rigorous limits for hadronic and semi-leptonic CP-violating coupling constants from the electric dipole moment of Hg
Yashpal Singh, B. K. Sahoo
Relativistic many-body methods at different levels of approximations are employed to gain insights into the passage of the electron correlations from lower to higher levels in the…
Quadrupole Shifts for the Yb Ion Clocks: Experiments versus Theories
D. K. Nandy, B. K. Sahoo
Quadrupole shifts for three prominent clock transitions, , an…
Triple excitations in perturbed relativistic coupled-cluster theory and Electric dipole polarizability of groupIIB elements
S. Chattopadhyay, B. K. Mani, D. Angom
We use perturbed relativistic coupled-cluster (PRCC) theory to compute the electric dipole polarizabilities of Zn, Cd and Hg. The computations are done using the Dirac-Coulomb-…
A Relativistic Equation-of-motion Coupled-Cluster Investigation of the Trends of Single and Double Ionization Potentials in the He and Be Isoelectronic Systems
Himadri Pathak, B. K. Sahoo, Turbasu Sengupta +3
We employ four-component spinor relativistic equation-of-motion coupled-cluster (EOMCC) method within the single- and double- excitation approximation to calculate the single ioniz…
Implementation and Application of the Relativistic Equation of Motion Coupled-cluster Method for the Excited States of Closed-shell Atomic Systems
D. K. Nandy, Yashpal Singh, B. K. Sahoo
We report the implementation of equation-of-motion coupled-cluster (EOMCC) method in the four-component relativistic framework with the spherical atomic potential to generate the e…
