Multi-configurational relativistic calculation of polarizabilities and multi-photon transition probabilities in many-electron atomic and ionic systems.
The purpose of our PhD thesis is to extend the computational tools of atomic structures to static and dynamic polarizabilities, hyperpolarizabilities and multi-photon transition probabilities. Relativistic hydrogen-like systems will be treated by the Lagrange-mesh method, as an extension of our Master thesis, for properties not considered in this work. The extension to many-electron systems will be realized in the field of multi-configurational Hartree-Fock and Dirac-Fock approaches which need new theoretical, methodological and computational developments. The codes based on these methods enable the calculation of a large number of spectroscopic properties, excluding polarizabilities and multi-photon transition probabilities. We will thus develop computational tools in order to fill in this gap.
Atomic and ionic polarizabilities appear directly or indirectly in a large number of fields and applications, namely in cold atoms physics, metrology and chemical physics.
Multi-photon transitions are part of a priori highly unlikely processes and are therefore called « forbidden » radiative processes. Meanwhile experimental situations exist in which metastable excited states decay through these channels. Long lifetimes were measured for highly charged Be-like ions in recent storage-ring experiments, but some problems appear in their interpretation. The study of the competition between « forbidden » (one-photon beyond the dipole approximation, or multi-photon) and « unexpected » (hyperfine-induced or induced by external fields) radiative processes is all obviously relevant.
