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…
Electric quadrupole moment of the state in and its role in an optical frequency standard
Chiranjib Sur, K. V. P. Latha, Rajat K. Chaudhuri +2
The electric quadrupole moment for the state of , one of the most important candidates for an optical clock, has been calculated using the relati…
Case studies of atomic properties using coupled-cluster and unitary coupled-cluster methods
Chiranjib Sur, Rajat K. Chaudhuri, B. P. Das +1
The magnetic dipole and electric quadrupole hyperfine constants of Aluminium () atom are computed using the relativistic coupled cluster (CC) and unitary coupled cluster (…
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…
Coupled Electron Pair Approximation Calculation of the Electric Dipole Moment of Atomic Yb
Angom Dilip Singh, Bhanu Pratap Das, Debashis Mukherjee
The existence of a finite electric dipole moment (EDM) d_a of the closed-shell atom Yb implies parity and time reversal violations involving the nuclear sector. An important effect…
