Symmetry breaking in atomic multi-configuration calculations
Seminar Room 1, Newton Institute
AbstractThe multiconfiguration Dirac-Fock method allows to calculate the bound states of relativistic electrons in atoms or molecules. For a long time, this method has been known to provide certain "wrong" predictions in the nonrelativistic limit. By describing in detail the nonlinear model obtained in the nonrelativistic limit for Berilyum-like atoms, we will show the origin of this phenomenon which is actually linked to symmetry breaking in the angular momentum of the configurations. (These results are contained in a joint work with Mathieu Lewin and Andreas Savin).
If it doesn't, something may have gone wrong with our embedded player.
We'll get it fixed as soon as possible.
