We carried out a detailed high-precision study of Ag-like ${\mathrm{Nd}}^{13+}$ and ${\mathrm{Sm}}^{15+}$ and In-like ${\mathrm{Ce}}^{9+}$, ${\mathrm{Pr}}^{10+}$, ${\mathrm{Nd}}^{11+}$, ${\mathrm{Sm}}^{13+}$, and ${\mathrm{Eu}}^{14+}$ highly charged ions. These ions were identified to be of particular interest for the development of ultra-accurate atomic clocks, the search for variation of the fine-structure constant $\ensuremath{\alpha}$, and quantum information [Safronova et al., Phys. Rev… 
5p−4f level crossing in palladium-like ions and its effect on metastable states
We study the level structures of palladium-like ${\mathrm{I}}^{7+}$ $(Z=53)$ and ${\mathrm{Ba}}^{10+}$ $(Z=56)$ and the behavior of their metastable states with an electron beam ion trap. The
Actinide ions for testing the spatial α -variation hypothesis
Testing the spatial variation of fine-structure constant $\alpha$ indicated in [Webb et al., Phys. Rev. Lett. 107, 191101 (2011)] with terrestrial laboratory atomic measurements requires at least
Theoretical investigation on forbidden transition properties of fine-structure splitting in 2 D state for K-like ions with $\boldsymbol{26}{\leqslant} {\boldsymbol{Z}}\leqslant \boldsymbol{36}$
Excitation energies, magnetic dipole, and electric quadrupole transition probabilities of the transition in the potassium-like (K-like) sequence with are investigated by using the multi-configuration
Quadruply Ionized Barium as a Candidate for a High-Accuracy Optical Clock.
The differential static scalar polarizability is found to be small and negative, providing suppressed sensitivity to blackbody radiation while simultaneously allowing cancellation of Stark and excess micromotion shifts.
Optical clocks based on the Cf15+ and Cf17+ ions
Recent experimental progress in cooling, trapping, and quantum logic spectroscopy of highly charged ions (HCIs) made HCIs accessible for high-resolution spectroscopy and precision fundamental
Highly charged ions for atomic clocks and search for variation of the fine structure constant
We review a number of highly charged ions which have optical transitions suitable for building extremely accurate atomic clocks. This includes ions from Hf 12+ to U 34+, which have the 4f12
Atomic properties and transition parameters of highly charged Sb-like isoelectronic ions
The atomic properties and transition parameters of Sb-like Cs4+, Ba5+, La6+, Ce7+, Pr8+, Nd9+, Pm10+, and Sm11+ ions were first calculated using the GRASP2K package. This method is based on the
A cryogenic radio-frequency ion trap for quantum logic spectroscopy of highly charged ions.
Using this trap in conjunction with an electron beam ion trap and a deceleration beamline, it is able to trap single highly charged Ar13+ (Ar XIV) ions concurrently with single Be+ ions, a key prerequisite for the first quantum logic spectroscopy of a HCI.
Frequency metrology using highly charged ions
Due to the scaling laws of relativistic fine structure splitting, many forbidden optical transitions appear within the ground state configurations of highly charged ions (HCI). In some hydrogen-like
New Methods for Testing Lorentz Invariance with Atomic Systems.
A broadly applicable experimental proposal to search for the violation of local Lorentz invariance (LLI) with atomic systems using dynamic decoupling and can be implemented in current atomic clock experiments, with both single ions and arrays of neutral atoms.
