We study the structure and ionization/scattering dynamics of atomic systems using theoretical and computational methods. These systems can be simple atoms or exotic systems such as atoms trapped in a fullerene (endohedral systems) or it can be a group of atoms (clusters). We explore these systems with a fundamental point of view to get a rigorous understanding of the electron-electron interactions, relativistic effects and also to know how the properties of atomic systems get modified by the presence of an external cage. We also study the dynamics of ionization in the time domain (atto-second spectroscopy) to get deeper insights to the ionization process. The photoelectron/scattered electrons are the information carriers of the target. By studying them systematically, we can extract all the required information. A deep knowledge on ionization and scattering processes play an important role in nano-science, developing quantum technologies, plasmonics and xuv lithography etc.
