Fock-space perturbed relativistic coupled-cluster theory for electric dipole polarizability of one-valence atomic systems: Application to Al and In
Ravi Kumar, D. Angom, B. K. Mani
We have developed a Fock-space relativistic coupled-cluster theory based method for the calculation of electric dipole polarizability of one-valence atoms and ions. We employ this…
RCC calculation of electric dipole polarizability and correlation energy of Cn, Nh and Og: Correlation effects from lighter to superheavy elements
Ravi Kumar, S. Chattopadhyay, D. Angom +1
We employ a fully relativistic coupled-cluster theory to calculate the ground-state electric dipole polarizability and electron correlation energy of superheavy elements Cn, Nh…
Fock-space relativistic coupled-cluster calculation of hyperfine induced clock transition in Al
Ravi Kumar, S. Chattopadhyay, D. Angom +1
We have developed an all-particle Fock-space relativistic coupled-cluster method to calculate the properties of two-valence atoms and ions. Using the method we compute the properti…
Electric dipole polarizability of group-IIIA ions using PRCC: Large correlation effects from nonlinear terms
Ravi Kumar, S. Chattopadhyay, B. K. Mani +1
We compute the ground-state electric dipole polarizability of group-IIIA ions using the perturbed relativistic coupled-cluster (PRCC) theory. To account for the relativistic effect…
RCCPAC: A parallel relativistic coupled-cluster program for closed-shell and one-valence atoms and ions in FORTRAN
B. K. Mani, Siddhartha Chattopadhyay, D. Angom
We report the development of a parallel FORTRAN code, RCCPAC, to solve the relativistic coupled-cluster equations for closed-shell and one-valence atoms and ions. The parallelizati…
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-…
