Sixth-order Coulomb correlations identified in a semiconductor single quantum well
2001
Summary form only given. The nonlinear optical response in semiconductors has traditionally been treated in a mean field approximation at the 2-particle level. Recent work, in particular comparisons of four-wave mixing (FWM) with microscopic theory, have demonstrated the importance of 4-particle correlations. Such experiments, however, are not optimally sensitive to correlations at the 6-particle level. In order to probe such six-particle correlations, we compare the results of six-wave mixing (SWM) measurements with a detailed microscopic theory based on the dynamics controlled truncation scheme (DCT). Experiments were performed on a single 5 nm ZnSe quantum well.
