Collective Spin-Flip Excitations in the Quantum Hall Regime,gnetoplasmons and spin-waves, which, at long wavelengths, can be probed by cyclotron resonance and electron spin resonance experiments. To first order, electron-electron interactions only affect these modes at finite wave vectors and, hence, their effect is not directly probed by such experiments. R

Coulomb Perturbation by Photoholes of Two-Dimensional Electron Gas Ingaas-Heterojunctions: the Casemensional (2D) electron gas in quantizing magnetic fields in the integer and fractional quantum Hall regimes, and beyond . A critical question, of course, is the nature of the connection between such optical information and that derived from transport experiments, specifically in terms of the p

Photoluminescence Spectroscopy of Incompressible Electron Liquid States in GaAs,dimensional electrons and photoexcited valence band holes is fundamental in determining the photoluminescence spectrum. Measurements of a low-density electron system reveal a distinct Fermi edge singularity at zero and low magnetic fields, indicating strong multiple conduction-band electron-hole sca

Optical Spectroscopy in the Regimes of the Integer and Fractional Quantum Hall Effects,fractional quantum Hall effects. The goal of such studies is the discovery of new behaviors that are not accessible in magnetotransport experiments. The seminal photoluminescence measurements were reported in Si mosfet devices and in multiple GaAs-AlGaAs quantum wells . The optical recombinat

Magneto-Optics of the Fractional Quantum Hall Effect: Theory,ifest themselves in the optical spectra only when a hidden symmetry inherent in the magnetospectroscopy of such systems is violated. As a result, spectra are variable, and depend on the mutual magnitudes of different perturbations. In particular, the dispersion law of magnetoexcitons strongly depend

Photoluminescence in the Fractional Quantum Hall Effect,rse magnetic field. It exhibits dissipationaless conduction ρ. = 0 and quantization of the Hall resistance R. = hv/e , with v-the Landau level filling number-a rational fraction. This paper will address the magneto-optics of quantum Hall states. For ideal system of coplanar electrons and holes the p

Exciton Unbinding in the Quasi-Two-Dimensional Electron Gas,a finite hole mass and bound excitonic states. A mean-field theory is employed which allows a consistent treatment of magnetic-field dependent screening in the integer quantum Hall regime. It is argued that higher-order scattering effects are difficult to identify by experiment. Recent luminescence

Femtosecond Coherent Spectroscopy of Semiconductor Nanostructures, part, we discuss femtosecond time evolution of FWM signals from high quality intrinsic GaAs quantum wells. These results show unambiguously that the generally-neglected Coulomb interaction effects between excitons dominate the time-resolved and time-integrated FWM signals. The results also show
