Time- and parity-violating effects of nuclear Schiff moment in molecules and solids
V. V. Flambaum, V. A. Dzuba, H. B. Tran Tan
We show that existing calculations of the interaction between nuclear Schiff moments and electrons in molecules use an inaccurate operator which gives rise to significant errors. B…
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…
Electric dipole moments of atoms and molecules produced by enhanced nuclear Schiff moments
V. V. Flambaum, V. A. Dzuba
We perform calculations of the CP-violating atomic and molecular electric dipole moments (EDM) induced by the interaction of the nuclear Schiff moments with electrons. EDM of atoms…
Fast apparent oscillations of fundamental constants
Dionysios Antypas, Dmitry Budker, Victor V. Flambaum +3
Precision spectroscopy of atoms and molecules allows one to search for and to put stringent limits on the variation of fundamental constants. These experiments are typically interp…
High Resolution Photoexcitation Measurements Exacerbate the Long-Standing Fe XVII Oscillator Strength Problem
Steffen Kühn, Chintan Shah, José R. Crespo López-Urrutia +29
For more than 40 years, most astrophysical observations and laboratory studies of two key soft x-ray diagnostic transitions, and , in Fe XVII ions found oscillator…
Detection of the orbital crossing and its optical clock transition in Pr
H. Bekker, A. Borschevsky, Z. Harman +5
Recent theoretical works have proposed atomic clocks based on narrow optical transitions in highly charged ions. The most interesting candidates for searches of new physics are tho…
Theoretical calculation of atomic properties of superheavy elements Z=110-112 and their ions
B. G. C. Lackenby, V. A. Dzuba, V. V. Flambaum
We calculate the spectra, electric dipole transition rates and isotope shifts of the super heavy elements Ds (Z=110), Rg (Z=111) and Cn (Z=112) and their ions. These calculations w…
Isotope shifts in Ne -- Precision measurements and global analysis in the framework of intermediate coupling
B. Ohayon, H. Rahangdale, A. J. Geddes +2
We report new precision measurements of the Ne--Ne isotope shift for several transitions, as well as state-of-the-art, \textit{ab initio} field-shift calculations. Ou…
High-precision ab initio calculations of the spectrum of Lr
E. V. Kahl, J. C. Berengut, M. Laatiaoui +2
The planned measurement of optical resonances in singly-ionised lawrencium (Z = 103) requires accurate theoretical predictions to narrow the search window. We present high-precisio…
A Simple Explanation for the Observed Power Law Distribution of Line Intensity in Complex Many-Electron Atoms
Keisuke Fujii, Julian C. Berengut
It has long been observed that the number of weak lines from many-electron atoms follows a power law distribution of intensity. While computer simulations have reproduced this depe…
Sensitivity of isotope shift to distribution of nuclear charge density
V. V. Flambaum, V. A. Dzuba
It is usually assumed that the field isotope shift (FIS) is completely determined by the change of the averaged squared values of the nuclear charge radius . Re…
Blackbody radiation shift for the S--P optical clock transition in zinc and cadmium atoms
Vladimir A. Dzuba, Andrei Derevianko
Black-body radiation (BBR) shifts of clock transition in divalent atoms Cd and Zn are evaluated using accurate relativistic many-body techniques of atomic structu…
Theoretical study of YbOH to search for the nuclear magnetic quadrupole moment
Daniel E. Maison, Leonid V. Skripnikov, Victor V. Flambaum
CP-violating interaction of the nuclear magnetic quadrupole moment (MQM) with electrons in the ytterbium mono-hydroxide molecule, YbOH, is considered. Both the magnetic qua…
Calculations of the atomic structure for the low-lying states of actinium
V. A. Dzuba, V. V. Flambaum, B. M. Roberts
We employ a technique that combines the configuration interaction method with the singles-doubles coupled-cluster method to perform calculation of the energy levels, transition amp…
Theoretical study of electron structure of superheavy elements with an open -shell, Sg, Bh, Hs and Mt
B. G. C. Lackenby, V. A. Dzuba, V. V. Flambaum
We use recently developed efficient versions of the configuration interaction method to perform {\em ab initio} calculations of the spectra of superheavy elements seaborgium (Sg, $…
Isotopic variation of parity violation in atomic ytterbium: method of measurements and analysis of systematic effects
D. Antypas, A. M. Fabricant, J. E. Stalnaker +3
We present a detailed description of experimental studies of the parity violation effect in an isotopic chain of atomic ytterbium (Yb), whose results were reported in a recent Lett…
Dependence of atomic parity-violation effects on neutron skins and new physics
A. V. Viatkina, D. Antypas, M. G. Kozlov +2
We estimate the relative contribution of nuclear structure and new physics couplings to the parity non-conserving spin-independent effects in atomic systems, for both single isotop…
