1. Theoretical Atomic Spectroscopy of Earthbound and Stellar Plasma
Abstract : Motivated by spectroscopic analysis of astrophysical and laboratory plasma, this thesis concerns the fundamental structure and spectral properties of atoms and their ions. The multiconfiguration Dirac-Hartree-Fock (MCDHF) method is used to predict the emission or absorption of radiation, by atomic systems in general, and of heavy and highly charged ions in particular.

2. Computing attosecond delays in atomic photoionisation : A non-iterative method for many-electron correlation within the Random Phase Approximation with Exchange
Abstract : När en atom absorberar fotoner, i växelverkan med tillräckligt högenergetisktljus, så kan en (eller flera) av atomens elektroner ”sparkas ut”. Det resulterar i en positivt laddad jon och en (eller flera) så kallade fotoelektroner. Den här processen är känd som den fotoelektriska effekten, men kallas också för fotojonisering. READ MORE
