Higher Energy Composite Fermion Levels in the Fractional Quantum Hall Effect
Trevor D. Rhone, Dwipesh Majumder, Brian S. Dennis +9
Even though composite fermions in the fractional quantum Hall liquid are well established, it is not yet known up to what energies they remain intact. We probe the high-energy spec…
Observation of non-conventional spin waves in composite fermion ferromagnets
U. Wurstbauer, S. S. Mandal, D. Majumder +8
We find unexpected low energy excitations of fully spin-polarized composite-fermion ferromagnets in the fractional quantum Hall liquid, resulting from a complex interplay between a…
Spin-texture and magneto-roton excitations at nu=1/3
Javier G. Groshaus, Irene Dujovne, Yann Gallais +7
Neutral spin texture ST excitations at nu=1/3 are directly observed for the first time by resonant inelastic light scattering. They are determined to involve two simultaneous spin-…
Transition from Free to Interacting Composite Fermions away from =1/3
Y. Gallais, T. H. Kirschenmann, I. Dujovne +5
Spin excitations from a partially populated composite fermion level are studied above and below . In the range the experiments uncover significant departures fro…
Spin excitations in the Fractional Quantum Hall regime at
Y. Gallais, T. H. Kirschenmann, C. F. Hirjibehedin +4
We report inelastic light scattering experiments in the fractional quantum Hall regime at filling factors . A spin mode is observed below the Zeeman energy. The filli…
Splitting of Long-Wavelength Modes of the Fractional Quantum Hall Liquid at
C. F. Hirjibehedin, Irene Dujovne, A. Pinczuk +3
Resonant inelastic light scattering experiments at reveal a novel splitting of the long wavelength modes in the low energy spectrum of quasiparticle excitations in the char…
