## Abstract

The signatures of carrier correlations are investigated using a microscopic model which fully includes four particle (two electrons-two holes) correlations within the coherent χ^{(3)} limit. In this one-dimensional tight binding model, two spin-degenerate electron and heavy-hole bands are considered and the usual circularly-polarized dipole matrix elements describing the optical transitions between these bands are used. The optical response within this model is computed in the coherent χ^{(3)} limit without further approximation. Solutions of the relevant equations of motion for a one-dimensional tight binding model are obtained without any assumptions about the nature of bound and unbound two-exciton states.
