New bounds on the excess charge for bosonic systems interacting through Coulomb potentials

The following research results, whose main goal was to establish new upper bounds for the excess charge for an atom, are collected in this PhD thesis. Such an atom consists of a fixed, classical nucleus of charge $Z$ (Born-Oppenheimer approximation) and $N$ non-relativistic quantum particles (Hartree approximation). A...
