Symmetry breaking in atomic multi-configuration calculations

Wednesday 1st August 2012 - 09:45 to 10:30
INI Seminar Room 1
The 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).
