Fast configuration-interaction calculations for nobelium and ytterbium
V. A. Dzuba, V. V. Flambaum, M. G. Kozlov
We calculate excitation energies for low states of nobelium, including states with open subshell. An efficient version of the many-electron configuration-interaction method fo…
Screening and enhancement of oscillating electric field in molecules
H. B. Tran Tan, V. V. Flambaum, I. B. Samsonov
According to the Schiff theorem, the atomic electrons completely screen the atomic nucleus from an external static electric field. However, this is not the case if the field is tim…
Resonant electronic-bridge excitation of the U-235 nuclear transition in ions with chaotic spectra
J. C. Berengut
Electronic bridge excitation of the 76 eV nuclear isomeric state in U is shown to be strongly enhanced in the U ion, potentially enabling laser excitation of this nu…
HfF as a candidate to search for the nuclear weak quadruple moment
L. V. Skripnikov, A. N. Petrov, A. V. Titov +1
Nuclei with a quadrupole deformation such as Hf have enhanced weak quadrupole moment which induces the tensor weak electron-nucleus interaction in atoms and molecules. Corr…
Nobelium energy levels and hyperfine structure constants
S. G. Porsev, M. S. Safronova, U. I. Safronova +2
Advances in laser spectroscopy of superheavy () elements enabled determination of the nuclear moments of the heaviest nuclei, which requires high-precision atomic calculatio…
Resonant enhancement of oscillating electric field in atom
V. V. Flambaum, I. B. Samsonov
When an atom is placed into an oscillating electric field with frequency far from atomic resonances, the atomic electrons partly shield this field at the nucleus. It is conjectured…

Bryce G. C. Lackenby, Vladimir A. Dzuba, Victor V. Flambaum
We calculate the spectrum and allowed E1 transitions of the superheavy element Og (Z=118). A combination of configuration interaction (CI) and perturbation theory (PT) is used (Dzu…
The nuclear anapole moment interaction in BaF from relativistic coupled cluster theory
Yongliang Hao, Miroslav Ilias, Ephraim Eliav +3
We present high accuracy relativistic coupled cluster calculations of the P-odd interaction coefficient describing the nuclear anapole moment effect on the molecular electron…
Enhanced nuclear Schiff moment and time reversal violation in 229Th-containing molecules
V. V. Flambaum
Octupole deformation results in a strongly enhanced collective Schiff moment in 229Th nucleus. An additional enhancement of time reversal (T) and parity (P) violating effects (such…
Energy Level Structure of Sn Ions
J. Scheers, A. Ryabtsev, A. Borschevsky +10
Laser-produced Sn plasma sources are used to generate extreme ultraviolet (EUV) light in state-of-the-art nanolithography. An ultraviolet and optical spectrum is measured from a dr…
Screening of oscillating external electric field in atoms
V. A. Dzuba, J. C. Berengut, J. S. M. Ginges +1
We study the screening of a homogeneous oscillating external electric field in noble-gas atoms using atomic many-body calculations. At zero frequency of the oscillations ($ω=…
Searches for New Particles Including Dark Matter with Atomic, Molecular and Optical Systems
Yevgeny V. Stadnik, Victor V. Flambaum
New particles can manifest their effects in many settings, ranging from effects on sub-atomic to galactic length scales. The nature of these effects depends on the specific particl…
Saturated configuration interaction calculations for five-valent Ta and Db

E. V. Kahl, J. C. Berengut
We present the AMBiT software package for general atomic structure calculations. This software implements particle-hole configuration interaction with many-body perturbation theory…
New constraints on axion-mediated P,T-violating interaction from electric dipole moments of diamagnetic atoms
V. A. Dzuba, V. V. Flambaum, I. B. Samsonov +1
The exchange of an axion-like particle between atomic electrons and the nucleus may induce electric dipole moments (EDMs) of atoms and molecules. This interaction is described by a…

Atomic spectra and other properties of superheavy element dubnium (Db, Z=105) are calculated using recently developed method combining configuration interaction with perturbation t…
Enhanced nuclear spin dependent parity violation effects using the 199HgH molecule
A. J. Geddes, L. V. Skripnikov, A. Borschevsky +3
Electron interactions with the nuclear-spin-dependent (NSD) parity non-conserving (PNC) anapole moment are strongly enhanced within heteronuclear diatomic molecules. A novel, low-e…
Shielding of an external oscillating electric field inside atoms
V. V. Flambaum
According to the Schiff theorem an external electric field vanishes at atomic nucleus in a neutral atom, i.e. it is completely shielded by electrons. This makes a nuclear electric…
