Gaussian basis set approach to one-loop self-energy
Dávid Ferenc, Maen Salman, Trond Saue
We report a method for the evaluation of the one-loop self-energy, to all orders in the external binding field, using a Gaussian basis set expansion. This choice of basis is motiva…

Regularized relativistic corrections for polyelectronic and polyatomic systems with explicitly correlated Gaussians
Balázs Rácsai, Dávid Ferenc, Ãdám Margócsy +1
Drachmann's regularization approach is implemented for floating explicitly correlated Gaussians (fECGs) and molecular systems. Earlier applications of drachmannized relativistic co…
