Paper Abstract

We present a review of our recent resonant inelastic light scattering research of the ultra-high mobility two-dimensional electron gas in GaAs quantum wells. Spectroscopy of intersubband excitations shows that exchange interactions are larger than previously anticipated. Light scattering by large wavevector inter-Landau-level excitations displays the excitonic binding and roton minima in the mode dispersions that are predicted by Hartree-Fock theories.
