Abstract

For a proper understanding of nonlinear optical experiments in semiconductors even the low-density limit Coulomb-induced manybody correlations beyond the Hartree-Eock decoupling scheme need to be considered. In the coherent χ⁽³⁾ limit these correlations manifest themselves in the contributions of bound and unbound two-exciton states to the optical response.^1–4 The understanding of nonlinear excitonic effects in the Stark effect of semiconductors including carrier-correlations is still of fundamental interest.
