Relativistic Coupled-Cluster Theory of Atomic Parity Nonconservation: Application to Ba
Bijaya K. Sahoo, Rajat Chaudhuri, B. P. Das +1
We report the result of our {\it ab initio} calculation of the parity nonconserving electric dipole transition amplitude in base…
A New Limit for the Coupling Constant of the Electron-Nucleus Scalar-Pseudoscalar Interaction
Bijaya K. Sahoo, Rajat K. Chaudhuri, B. P. Das +2
We report the results of our calculations of the atomic electric dipole moments of cesium and thallium arising from the electron-nucleus scalar-pseudoscalar interaction. The calcul…
Relativistic and correlation effects in atoms
B. P. Das, K. V. P. Latha, Bijaya K. Sahoo +3
This review article deals with some case studies of relativistic and correlation effects in atomic systems. After a brief introduction to relativistic many-electron theory, a numbe…
Relativistic unitary coupled cluster theory and applications
Chiranjib Sur, Rajat K Chaudhuri, Bijaya K. Sahoo +2
We present the first formulation and application of relativistic unitary coupled cluster theory to atomic properties. The remarkable features of this theory are highlighted, and it…
