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

Relativistic equation-of-motion coupled-cluster method for the double ionization potentials of the closed-shell atoms
Himadri Pathak, Aryya Ghosh, B. K. Sahoo +3
We report the general implementation of the relativistic equation-of-motion coupled-cluster method to calculate double ionization spectra (DI-EOMCC) of atomic and molecular systems…
Relativistic Spectroscopy of Plasma Embedded Li-like Systems with the Screening Effects in the Two-body Debye Potentials
Madhulita Das, B. K. Sahoo, Sourav Pal
The spectroscopic properties of Li atom and Li-like Ca and Ti ions in the plasma environment are investigated using a relativistic coupled-cluster (RCC) method. Assuming the plasma…
Relativistic Equation of Motion Coupled-Cluster Method: Application to the closed-shell atomic systems
Himadri Pathak, B. K. Sahoo, B. P. Das +2
We report our successful implementation of the full fledged relativistic equation of motion coupled cluster (EOMCC) method. This method is employed to compute the principal ionizat…
