Demonstrating Correlation Trends in the Electric Dipole Polarizabilities of Many Low-lying States in Cs I through First-principle Calculations
A. Chakraborty, B. K. Sahoo
Electron correlation and higher-order relativistic effects are probed in the evaluation of scalar and tensor static electric dipole (E1) polarizabilities () of several even- a…
Ab initio Calculations of Electric Dipole Polarizabilities in the Li, Na and K Atoms
A. Chakraborty, B. K. Sahoo
We carry out first-principle calculations of scalar and tensor components of the static electric dipole polarizabilities of six low-lying states of lithium (Li), sodium (Na) and po…
High-accuracy Nuclear Spin Dependent Parity Violating Amplitudes in Cs
A. Chakraborty, B. K. Sahoo
Relativistic coupled-cluster (RCC) theory at the singles and doubles approximation has been implemented to estimate nuclear spin dependent (NSD) parity violating (PV) electric dipo…
