Collective effects in excitonic free induction decay: Do semiconductors and atoms emit coherent light in different ways?

We show that the many-body interactions among excitons govern the temporal line shape of the coherent (free induction decay) emission from semiconductor quantum walls. At low exciton densities, they become the dominant contribution to the emission.
