Domain Textures in the Fractional Quantum Hall Effect
Ziyu Liu, Ursula Wurstbauer, Lingjie Du +4
Impacts of domain textures on low-lying neutral excitations in the bulk of fractional quantum Hall effect (FQHE) systems are probed by resonant inelastic light scattering. We demon…
Observation of flat bands in gated semiconductor artificial graphene
Lingjie Du, Ziyu Liu, Shalom J. Wind +6
Flat bands near M points in the Brillouin zone are key features of honeycomb symmetry in artificial graphene (AG) where electrons may condense into novel correlated phases. Here we…
Observation of new plasmons in the fractional quantum Hall effect: interplay of topological and nematic orders
Lingjie Du, Ursula Wurstbauer, Ken W. West +5
Collective modes of exotic quantum fluids reveal underlying physical mechanisms responsible for emergent complex quantum ground states. We observe unexpected new collective modes i…
Collective electronic excitation in a trapped ensemble of photogenerated dipolar excitons and free holes revealed by inelastic light scattering
Sebastian Dietl, Sheng Wang, Dieter Schuh +5
Photogenerated excitonic ensembles confined in coupled GaAs quantum wells are probed by a complementary approach of emission spectroscopy and resonant inelastic light scattering. L…
Optical emission spectroscopy study of competing phases of electrons in the second Landau level
A. L. Levy, U. Wurstbauer, Y. Y. Kuznetsova +6
Quantum phases of electrons in the filling factor range are probed by the weak optical emission from the partially populated second Landau level and spin wave measu…
Fabrication of Artificial Graphene in a GaAs Quantum Heterostructure
Diego Scarabelli, Sheng Wang, Yuliya Y. Kuznetsova +7
The unusual electronic properties of graphene, which are a direct consequence of its two-dimensional (2D) honeycomb lattice, have attracted a great deal of attention in recent year…
