Light Scattering by Low Lying Quasiparticle Excitations in the Fractional Quantum Hall Regime
C. F. Hirjibehedin, Irene Dujovne, A. Pinczuk +3
Low lying excitations of electron liquids in the fractional quantum Hall (FQH) regime are studied by resonant inelastic light scattering methods. We present here results from charg…
Inhomogeneous CuO_{6} Tilt Distribution and Charge/Spin Correlations in La_{2-x-y}Nd_{y}Sr_{x}CuO$_{4} around commensurate hole concentration
A. Gozar, B. S. Dennis, T. Siegrist +2
Phononic and magnetic Raman scattering are studied in LaNdSrCuO with three doping concentrations: x ~ 1/8, y = 0; x ~ 1/8, y = 0.4; and x = 0.01, y = 0.…
Resonant Enhancement of Inelastic Light Scattering in the Fractional Quantum Hall Regime at
C. F. Hirjibehedin, Irene Dujovne, I. Bar-Joseph +4
Strong resonant enhancements of inelastic light scattering from the long wavelength inter-Landau level magnetoplasmon and the intra-Landau level spin wave excitations are seen for…
Spectroscopy of soft modes and quantum phase transitions in coupled electron bilayers
Stefano Luin, Irene Dujovne, Vittorio Pellegrini +6
Strongly-correlated two-dimensional electrons in coupled semiconductor bilayers display remarkable broken symmetry many-body states under accessible and controllable experimental c…
Soft Magnetorotons and Broken-Symmetry States in Bilayer Quantum Hall Ferromagnets
Stefano Luin, Vittorio Pellegrini, Aron Pinczuk +3
The recent report on the observation of soft magnetorotons in the dispersion of charge-density excitations across the tunneling gap in coupled bilayers at total Landau level fillin…
Light scattering observations of spin reversal excitations in the fractional quantum Hall regime
I. Dujovne, C. F. Hirjibehedin, A. Pinczuk +4
Resonant inelastic light scattering experiments access the low lying excitations of electron liquids in the fractional quantum Hall regime in the range . Modes…
