Recent developments in frequency metrology and optical clocks have been based on
electronic transitions in atoms and singly charged ions as references. The control over all …

Studying the violation of parity and time-reversal invariance in atomic systems has proven to
be a very effective means of testing the electroweak theory at low energy and searching for …

A model operator approach to calculations of the QED corrections to energy levels in
relativistic many-electron atomic systems is developed. The model Lamb shift operator is …

We present Fortran package QEDMOD for computing the model QED operator h QED that
can be used to account for the Lamb shift in accurate atomic-structure calculations. The …

We study two-neutrino (2 ν β β) and neutrinoless double-β (0 ν β β) decays in the nuclear
shell model and proton-neutron quasiparticle random-phase approximation (pnQRPA) …

High-accuracy calculations of atomic properties of the superheavy elements (SHE) up to
element 122 are reviewed. The properties discussed include ionization potentials, electron …

Generalized relativistic pseudopotentials (GRPP) of atomic cores implying the use of
different potentials for atomic electronic shells with different principal quantum numbers give …

Using recent high-precision measurements of electric dipole matrix elements of atomic
cesium, we make an improved determination of the scalar (α) and vector (β) polarizabilities …

The quantum electrodynamics (QED) corrections are directly incorporated into the most
accurate treatment of the correlation corrections for ions with complex electronic structure of …

We present a detailed study of the radiative potential method [VV Flambaum and JSM
