All-order extensions of relativistic atomic many-body perturbation theory are described and
applied to predict properties of heavy atoms. Limitations of relativistic many-body …

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 …

The recently established agreement between experiment and theory for the g factors of
lithiumlike silicon and calcium ions manifests the most stringent test of the many-electron …

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

Motivated by recent measurements for several alkali-metal atoms and alkali-metal-like ions,
we perform a detailed study of electric dipole (E 1) transition amplitudes in K, Ca+, Rb, Sr+ …

We propose methods and present calculations that can be used to search for evidence of
cosmic fields by investigating the parity-violating effects, including parity nonconservation …

Parity-violating energies E PV of the H2X2 (X= O, S, Se, Te, Po) molecules are reported,
calculated as analytical expectation values at the relativistic coupled-cluster singles-and …

We use the radiative potential method to perform a detailed study of quantum
electrodynamics (QED) radiative corrections to electric dipole (E1) transition amplitudes in …

A rigorous QED evaluation of the two-photon exchange corrections to the g factor of
lithiumlike ions is presented. The screened self-energy corrections are calculated for the …

In the presence of P-violating interactions, the exchange of vector bosons between electrons
and nucleons induces parity-nonconserving (PNC) effects in atoms and molecules, while the …
