We present an investigation of the dynamics of the inter-Landau-level (LL) excitations of a two-dimensional electron gas (2DEG) in large magnetic fields using coherent time-resolved nonlinear spectroscopy. The results are compared directly with measurements on undoped quantum wells. We observe time-dependent Coulomb coupling between the LL's induced by the 2DEG that induces a large transfer of ...
