抄録	Using GaAs/AlGaAs self-assembled quantum dots we study the few-particle dynamics of fully confined systems, which is associated with purely Coulomb interaction and is not affected by the internal strain field. Systematic evolution in the binding energies of positive and negative trions, as well as biexcitons, with dot size is interpreted in terms of a balance between the Hartree mean-field corrections on single-particle states and the interparticle correlations which lead to a nonseparable dynamics. The experimental behaviors are well reproduced by exact many-body calculations within the framework of the quantum Monte Carlo approach.
