Accurate determination of the electric dipole matrix elements, lifetimes, polarizabilities and light-shift ratios in Ba+ and Ra+
B. K. Sahoo, R. G. E. Timmermans, K. Jungmann
We have employed the relativistic coupled-cluster theory to calculate the electric dipole matrix elements in the singly ionized barium (Ba) and radium (Ra). Matrix elements…
Analysis of parity nonconservation in the Ra+-ion
L. W. Wansbeek, B. K. Sahoo, R. G. E. Timmermans +3
We report on a theoretical analysis of the suitability of the 7s 2S1/2 <-> 6d 2D3/2 transition in singly ionized radium to measure parity nonconservation, in the light of an experi…
Ab initio determination of polarizabilities and van der Waals coefficients of Li atoms using the relativistic CCSD(T) method
L. W. Wansbeek, B. K. Sahoo, R. G. E. Timmermans +2
We report a new technique to determine the van der Waals coeffcients of lithium (Li) atoms based on the relativistic coupled-cluster theory. These quantities are determined using t…
Phase separated charge density wave phase in two species extended Bose-Hubbard model
Tapan Mishra, B. K. Sahoo, Ramesh V. Pai
We study the quantum phase transitions in a two component bose-mixture in a one-dimensional optical lattice. The calculations have been performed in the framework of the extended B…
Intrinsic Electric Dipole Moments of Paramagnetic Atoms: Rubidium and Cesium
H. S. Nataraj, B. K. Sahoo, B. P. Das +1
The electric dipole moment (EDM) of paramagnetic atoms is sensitive to the intrinsic EDM contribution from that of its constituent electrons and a scalar--pseudo-scalar (S-PS) elec…
Electron correlation effects in the dipole polarizabilities of the ground states of Be, Mg, Ca, Sr, Ba and Yb
B. K. Sahoo, B. P. Das
We investigate the role of electron correlation effects in the electric dipole polarizabilities of the ground states of the alkaline earth and ytterbium atoms by employing the rela…
