Higher-order perturbative relativistic calculations for few-electron atoms and ions

Nuclear Instruments & Methods in Physics Research B, 2017
Abstract An effective computational method is developed for electronic-structure calculations in few-electron atoms and ions on the basis of the Dirac-Coulomb-Breit Hamiltonian. The recursive formulation of the perturbation theory provides an efficient access to the higher-order contributions of the interelectronic interaction.

Precise perturbative predictions from fixed-order calculations

open access: yesJournal of Physics G: Nuclear and Particle Physics, 2023
The intrinsic conformality is a general property of the renormalizable gauge theory, which ensures the scale-invariance of a fixed-order series at each perturbative order.
