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…
Nuclear Structure corrections for Parity Non-conservation in Atomic Ba and Ra
P. K. Panda, B. P. Das
We calculate the binding energy, charge radii in Ba--Ba and Ra--Ra using the relativistic mean field theory which includes scalar and vector mesons.…
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…
Electric quadrupole moment of the state in and its role in an optical frequency standard
Chiranjib Sur, K. V. P. Latha, Rajat K. Chaudhuri +2
The electric quadrupole moment for the state of , one of the most important candidates for an optical clock, has been calculated using the relati…
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…
