Abstract: We give an overview over some conjectured and known facts about the maximal number of electrons that atoms and quantum dots can bind. We discuss this in various contexts: experimentally, in simple density functionals, for atoms described by Schroedinger operators, and eventually for artificial atoms, so called quantum dots, in a graphene layer described by a pseudo-relativistic operator. The main result is based on joined work with Michael Handrek (Munich) and on a general Hardy type inequality obtained with Li Chen (Peking).
