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…
Prospects for optical clocks combining high sensitivity to new physics with insensitivity to perturbations; the case of Sb, Au, and Hg
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
Our study is motivated by the prospect of several metastable states in the Sb, Au, and Hg ions being used as possible candidates for optical clocks. We cal…
Calculation of the hyperfine structure of Dy, Ho, Cf, and Es
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
A recently developed version of the configuration interaction (CI) method for open shells with a large number of valence electrons has been used to study two heavy atoms, californi…
High-accuracy optical clocks based on group 16-like highly charged ions
Saleh O. Allehabi, S. M. Brewer, V. A. Dzuba +2
We identify laser-accessible transitions in group 16-like highly charged ions as candidates for high-accuracy optical clocks, including S-, Se-, and Te-like systems. For this class…
Atomic clocks highly sensitive to the variation of the fine structure constant based on Hf II, Hf IV, and W VI ions
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
We demonstrate that several metastable excited states in HfII, HfIV and WVI ions may be good clock states since they are sufficiently long-living and are not sensitive to…
Theoretical study of electronic structure of hafnium (Hf, Z=72) and rutherfordium (Rf, Z=104) atoms and their ions: Energy levels and hyperfine structure constants
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
Energy levels, magnetic dipole, and electric quadrupole hyperfine structure of the superheavy element rutherfordium (Rf, =104) and its first three ions are calculated using a co…
Using optical clock transitions in Cu II and Yb III for time-keeping and search for new physics
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum
We study the SD and SD transitions in Cu II and the SP transition in Yb III as possible candidates for the optical clock…
Nuclear deformation as a source of the non-linearity of King plot in the Yb ion
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum +1
We perform atomic relativistic many-body calculations of the field isotope shifts and calculations of corresponding nuclear parameters for all stable even-even isotopes of Yb i…
Time keeping and searching for new physics using metastable states of Cu, Ag and Au
V. A. Dzuba, Saleh O. Allehabi, V. V. Flambaum +2
We study the prospects of using the electric quadrupole transitions from the ground states of Cu, Ag and Au to the metastable state as clock transitions in optica…
Using isotope shift for testing nuclear theory: the case of nobelium isotopes
Saleh O. Allehabi, V. A. Dzuba, V. V. Flambaum +2
We calculate field isotope shifts for nobelium atoms using nuclear charge distributions which come from different nuclear models. We demonstrate that comparing calculated isotope s…
Theoretical study of electronic structure of erbium and fermium
Saleh O. Allehabi, Jiguang Li, V. A. Dzuba +1
We use a recently developed version of the configuration method for open shells to study electronic structure of erbium and fermium atoms. We calculate excitation energies of odd s…
