摘要：

We analyze few-particle 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 high photoexcitation density is given. (C) 1999 Elsevier Science B.V. All rights reserved.
