摘要：

We have performed a dynamical study of the blue shift and splitting of the exciton line in dense polarized exciton systems in quantum wells. The strong initial polarization of the excitons allows the separate evaluation of the strong repulsive part (due to the Pauli exclusion principle) and the small attractive part (due to the long range Coulomb effects) of the collective interactions between the excitons.
