Optical spectroscopy of complex open 4-shell ions Sn-Sn
F. Torretti, A. Windberger, A. Ryabtsev +8
We analyze the complex level structure of ions with many-valence-electron open [Kr] 4 sub-shells (=7-4) with ab initio calculations based on configuration…
Prediction of quantum many-body chaos in protactinium atom
A. V. Viatkina, M. G. Kozlov, V. V. Flambaum
Energy level spectrum of protactinium atom (Pa, Z=91) is simulated with a CI calculation. Levels belonging to the separate manifolds of a given total angular momentum and parity $J…
Combining configuration interaction with perturbation theory for atoms with large number of valence electrons
V. A. Dzuba, J. Berengut, C. Harabati +1
A version of the configuration interaction (CI) method is developed which treats highly excited many-electron basis states perturbatively, so that their inclusion does not affect t…
Electron structure of superheavy elements Uut, Fl and Uup (=113 to 115)
V. A. Dzuba, V. V. Flambaum
We use recently developed method of accurate atomic calculations which combines linearized single-double coupled cluster method with the configuration interaction technique to calc…
All-order calculations of the spectra of superheavy elements E113 and E114
T. H. Dinh, V. A. Dzuba
We apply a recently developed method (V. A. Dzuba, PRA 90, 012517 (2014); J. S. M. Ginges and V. A. Dzuba, PRA 91, 042505 (2015)) to calculate energy levels of superheavy elements…
Unexpectedly large difference of the electron density at the nucleus in the 4p P fine-structure doublet of Ca
C. Shi, F. Gebert, C. Gorges +9
We measured the isotope shift in the S-P (D2) transition in singly-ionized calcium ions using photon recoil spectroscopy. The high accuracy of the technique…
Limits on gravitational Einstein Equivalence Principle violation from monitoring atomic clock frequencies during a year
V. A. Dzuba, V. V. Flambaum
Sun's gravitation potential at earth varies during a year due to varying Earth-Sun distance. Comparing the results of very accurate measurements of atomic clock transitions perform…
Electron recombination with tungsten ions with open f-shells
C. Harabati, J. C. Berengut, V. V. Flambaum +1
We calculate the electron recombination rates with target ions W, -- , as functions of electron energy and electron temperature (i.e. the rates integrated over…
QED shifts in multivalent heavy ions
I. I. Tupitsyn, M. G. Kozlov, M. S. Safronova +2
The quantum electrodynamics (QED) corrections are directly incorporated into the most accurate treatment of the correlation corrections for ions with complex electronic structure o…
Search for the effect of massive bodies on atomic spectra and constraints on Yukawa-type interactions of scalar particles
N. Leefer, A. Gerhardus, D. Budker +2
We propose a new method to search for hypothetical scalar particles that have feeble interactions with Standard-Model particles. In the presence of massive bodies, these interactio…
Particle-hole configuration interaction and many-body perturbation theory: application to Hg+
J. C. Berengut
The combination of configuration interaction and many-body perturbation theory methods (CI+MBPT) is extended to non-perturbatively include configurations with electron holes below…
Improved limits on interactions of low-mass spin-0 dark matter from atomic clock spectroscopy
Y. V. Stadnik, V. V. Flambaum
Low-mass (sub-eV) spin-0 dark matter particles, which form a coherently oscillating classical field , can induce oscillating variations in the fundamental consta…
Atomic many-body effects and Lamb shifts in alkali metals
J. S. M. Ginges, J. C. Berengut
We present a detailed study of the Flambaum-Ginges radiative potential method which enables the accurate inclusion of quantum electrodynamics (QED) radiative corrections in a simpl…
Enhanced violation of the Lorentz invariance and Einstein's equivalence principle in nuclei and atoms
V. V. Flambaum
Local Lorentz Invariance violating (LLIV) and Einstein equivalence principle violating (EEPV) effects in atomic experiments are discussed. The EEPV effects are strongly enhanced in…
Ionization potentials and polarizabilities of superheavy elements from Db to Cn (=105 to 112)
V. A. Dzuba
Relativistic Hartree-Fock and random phase approximation methods for open shells are used to calculate ionization potentials and static scalar polarizabilities of eight superheavy…
Hyperfine-induced electric dipole contributions to the electric octupole and magnetic quadrupole atomic clock transitions
V. A. Dzuba, V. V. Flambaum
Hyperfine-induced electric dipole contributions may significantly increase probabilities of otherwise very weak electric octupole and magnetic quadrupole atomic clock transitions (…
Atomic Properties of Lu
Eduardo Paez, K. J. Arnold, Elnur Hajiyev +5
Singly ionised Lutetium has recently been suggested as a potential clock candidate. Here we report a joint experimental and theoretical investigation of \ce{Lu^+}. Measurements rel…
