| contents | Modeling plasmas in terms of atoms or ions is theoretically appealing for several reasons. When it is relevant, the notion of atom or ion in a plasma provides us with an interpretation scheme of the plasma's microscopic structure. From the standpoint of quantitative estimation of plasma properties, atomic models of plasma allow extending many theoretical tools of atomic physics to plasmas. This notably includes the statistical approaches to the detailed accounting for excited states, or the collisional-radiative modeling of non-equilibrium plasmas, which is based on the notion of atomic processes.
This habilitation thesis is mostly focused on the studies to which the author has contributed in the field of atomic modeling of dense, non-ideal plasmas. The studies to which the author contributed in the field of collisional-radiative modeling of non-LTE plasmas are also addressed, and the prospect of bridging with dense-plasma models is sketched. |
