Application of a Relativistic Coupled-Cluster Theory to the Effective Electric Field in YbF
M. Abe, G. Gopakumar, M. Hada +3
An accurate determination of the effective electric field (Eeff) in YbF is important, as it can be combined with the results of future experiments to give an improved new limit for…

Random Phase Approximation For allowed and Parity Non-conserving Electric Dipole Transition Amplitudes and its connection with Many-Body Perturbation Theory and Coupled Cluster Theory
Geetha Gopakumar, Chiranjib Sur, Bhanu Pratap Das +3
The connections between the Random Phase Approximation (RPA) and Many-Body Perturbation Theory (MBPT) and its all order generalisation, the Coupled- Cluster Theory (CCT) have been…
