A New Limit for the Coupling Constant of the Electron-Nucleus Scalar-Pseudoscalar Interaction
Bijaya K. Sahoo, Rajat K. Chaudhuri, B. P. Das +2
We report the results of our calculations of the atomic electric dipole moments of cesium and thallium arising from the electron-nucleus scalar-pseudoscalar interaction. The calcul…
Relativistic and correlation effects in atoms
B. P. Das, K. V. P. Latha, Bijaya K. Sahoo +3
This review article deals with some case studies of relativistic and correlation effects in atomic systems. After a brief introduction to relativistic many-electron theory, a numbe…
Relativistic unitary coupled cluster theory and applications
Chiranjib Sur, Rajat K Chaudhuri, Bijaya K. Sahoo +2
We present the first formulation and application of relativistic unitary coupled cluster theory to atomic properties. The remarkable features of this theory are highlighted, and it…
Comparative studies of the magnetic dipole and electric quadrupole hyperfine constants for the ground and low lying excited states of ^{25}Mg^{+}
Chiranjib Sur, Bijaya K. Sahoo, Rajat K Chaudhuri +2
We have employed the relativistic coupled cluster theory to calculate the magnetic dipole and electric quadrupole hyperfine constants for the ground and low lying excited states of…
