Vaibhav Katyal, B. K. Sahoo
Accurate determination of hyperfine structure constants in atomic systems provides important insight into the interplay of electron correlation and relativistic effects in the nucl…
Investigating Roles of Triple Excitations for High-precision Determination of Clock Properties of Alkaline Earth Metal Singly Charged Ions
A. Chakraborty, Vaibhav Katyal, B. K. Sahoo
High-accuracy calculations of electric dipole polarizabilities and quadrupole moments () of the clock states of the singly charged calcium (Ca), strontium (Sr) and bari…
Comprehensive Inclusion of Higher-order Ca Isotope Shifts in the King's Plot Yields an Order Improvement on the - Coupling Limit
Vaibhav Katyal, A. Chakraborty, B. K. Sahoo
By critically evaluating higher-order nonlinear effects to the isotope shifts (ISs) in the low-lying transition frequencies of the singly charged calcium ion, stringent constraint…
Cabibbo-Kobayashi-Maskawa unitarity deficit reduction via finite nuclear size
M Gorchtein, V Katyal, B Ohayon +2
We revisit the extraction of the CKM matrix element from the superallowed transition decay rate of AlMg, focusing on finite nuclear size effe…
Testing for isospin symmetry breaking with extensive calculations of isotope shift factors in potassium
Vaibhav Katyal, A. Chakraborty, B. K. Sahoo +4
Precise evaluation of the isotope shift (IS) factors for seven low-lying potassium (K) states is achieved using relativistic coupled-cluster (RCC) theory. The energies of these sta…
