We study the S0− D2 and S0− D3 transitions in Cu II and the S0− P2 transition in Yb III as possible candidates for the optical clock transitions. A recently developed version of the configuration (CI) method, designed for a large number of electrons above closed-shell core, is used to carry out the calculation. We calculate excitation energies, transition rates, lifetimes, scalar static polarizabilities of the ground and clock states, and blackbody radiation shift. We demonstrate that the… Expand

Two Clock Transitions in Neutral Yb for the Highest Sensitivity to Variations of the Fine-Structure Constant.
TLDR
This transition has a potential for high stability and accuracy and the advantage of the highest sensitivity among atomic clocks to variation of the fine-structure constant α, and opens new perspectives for searches for ultralight dark matter and for tests of theories beyond the standard model of elementary particles.

Transition frequency shifts with fine-structure constant variation for Yb II
In this paper we report calculations of the relativistic corrections to transition frequencies (q factors) of Yb II for the transitions from the odd-parity states to the metastable state 4f{supExpand
Frequency ratio of two optical clock transitions in 171Yb+ and constraints on the time variation of fundamental constants.
TLDR
This work presents the first direct measurement of the frequency ratio of these two clock transitions, without reference to a cesium primary standard, and using the same single ion of 171Yb+. Expand
Experimental and theoretical lifetimes in Yb III
Abstract:Lifetimes of three levels belonging to the configuration 4f135d with J = 1 in Yb III have been measured for the first time using the time-resolved laser-induced fluorescence method.Expand
Multipolar theory of blackbody radiation shift of atomic energy levels and its implications for optical lattice clocks
Blackbody radiation (BBR) shifts of the {sup 3}P{sub 0}-{sup 1}S{sub 0} clock transition in the divalent atoms Mg, Ca, Sr, and Yb are evaluated. The dominant electric-dipole contributions areExpand
New limits on coupling of fundamental constants to gravity using 87Sr optical lattice clocks.
The 1S0-3P0 clock transition frequency nuSr in neutral 87Sr has been measured relative to the Cs standard by three independent laboratories in Boulder, Paris, and Tokyo over the last three years. TheExpand
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 4f12Expand
Hyperfine quenching of the metastable 3 P 0,2 states in divalent atoms
Hyperfine quenching rates of the lowest-energy metastable 3 P 0 and 3 P 2 states of Mg, Ca, Sr, and Yb atoms are computed. The calculations are carried out using ab initio relativistic many-bodyExpand
Testing physics beyond the standard model through additional clock transitions in neutral ytterbium
We study the prospects of using transitions from the ytterbium ground state to metastable states at $E=19710.388~$cm$^{-1}$ and $E=23188.518~$cm$^{-1}$ as clock transitions in an optical latticeExpand
Highly charged ions for atomic clocks, quantum information, and search for α variation.
TLDR
Ten highly charged ions are proposed as candidates for the development of next generation atomic clocks, quantum information, and search for α variation and their properties crucial for the experimental exploration are predicted. Expand
