Dispersion C3 coefficients for the alkali-metal atoms interacting with a graphene layer and with a carbon nanotube
Bindiya Arora, Harjeet Kaur, B. K. Sahoo
We evaluate separation dependent van der Waal dispersion () coefficients for the interactions of the Li, Na, K and Rb alkali atoms with a graphene layer and with a single wall…
Electric dipole polarizability of alkaline-Earth-metal atoms from perturbed relativistic coupled-cluster theory with triples
S. Chattopadhyay, B. K. Mani, D. Angom
The perturbed relativistic coupled-cluster (PRCC) theory is applied to calculate the electric dipole polarizabilities of alkaline Earth metal atoms. The Dirac-Coulomb-Breit atomic…
Van der Waals Coefficients for the Alkali-metal Atoms in the Material Mediums
Bindiya Arora, B. K. Sahoo
The damping coefficients for the alkali atoms are determined very accurately by taking into account the optical properties of the atoms and three distinct types of trapping materia…
Correlation trends in the ground state static electric dipole polarizabilities of closed-shell atoms and ions
Yashpal Singh, B. K. Sahoo, B. P. Das
We employ the closed-shell perturbed relativistic coupled-cluster (RCC) theory developed by us earlier [Phys. Rev. A {\bf 77}, 062516 (2008)] to evaluate the ground state static el…
Development of a relativistic coupled-cluster method for one electron detachment theory: Application to Mn IX, Fe X, Co XI and Ni XII ions
D. K. Nandy, B. K. Sahoo
We have developed one electron detachment theory from a closed-shell atomic configuration in the relativistic Fock-space coupled-cluster ansatz. Using this method, we determine sen…
Experimental determination of the nuclear magnetic octupole moment of Ba ion
Nicholas C. Lewty, Boon Leng Chuah, Radu Cazan +2
We perform precision measurements on the 5D manifold hyperfine intervals of a single trapped ion, Ba. RF spectroscopy is used to measure the hyperfine intervals…
