We analyze excitonic and biexcitonic effects in the coherent optical spectra of semiconductor quantum dots using a density-matrix approach, that explicitly accounts for exciton-exciton interactions. A consistent description of additional peaks appearing at higher photoexcitation density is given.

Abstract
We analyze excitonic and biexcitonic effects in the coherent optical spectra of semiconductor quantum dots using a density-matrix approach, that explicitly accounts for exciton-exciton interactions. A consistent description of additional peaks appearing at higher photoexcitation density is given.
