Using the method of few-body physics, the solutions of low-lying states of negative donor centers in a GaAs parabolic quantum dot have been obtained. The dependence of the binding energy of the D y center on the quantum dot radius is also studied.

A density matrix approach has been employed to study analytically the absorption spectra of small semiconductor quantum dots under the strong confinement regime. The results are obtained for a single quantum dot (SQD) as well as for inhomogeneous distribution of quantum dots (IQDs) with Gaussian dis
