Hf ion: Highly Charged Ion for Next-Generation Atomic Clocks and Tests of Fundamental Physics
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
We use advanced computational techniques to study the electronic structure of the Hf ion, with the goal of assessing its potential for use in highly accurate atomic optical…
Isotope shift for total electron binding energy of atoms
V. A. Dzuba, V. V. Flambaum
We compute the isotope shifts of the \emph{total} electron binding energy of neutral atoms and singly charged ions up to element , using relativistic Hartree-Fock method inc…
Electronic structure calculation for superheavy elements Livermorium (Lv, Z=116) and Tennessine (Ts, Z=117) and their lighter analogs Te, I, Po, and At
V. A. Dzuba, V. V. Flambaum, G. K. Vong
Advanced theoretical techniques that combine the linearized coupled-cluster method, configuration interaction method, and perturbation theory are used to calculate energy levels, i…
Nuclear clock based on the Th V ion
V. A. Dzuba, V. V. Flambaum, E. Peik
We propose that a nuclear clock based on the Th V ion can surpass the accuracy of clocks built with other thorium ions. The Th ion has a rigid closed-shell core with zero to…
Resonance nuclear excitation of the Th nucleus via electronic bridge process in Th~II
V. A. Dzuba, V. V. Flambaum
The 8.4 eV transition in the Th nucleus is the basis for a high-precision nuclear clock with exceptional sensitivity to new physics effects. We have identified several case…
Using the Th III Ion for a Nuclear Clock and Searches for New Physics
V. A. Dzuba, V. V. Flambaum
The 229Th nucleus possesses a unique low-frequency transition at 8.4 eV, which is being considered for the development of an extremely accurate nuclear clock. We investigate an ele…
