We show that the resistance of the ν=5/2 quantum Hall state, confined to an interferometer, oscillates with the magnetic field consistent with an Ising-type non-Abelian state. In three quantum Hall interferometers of different sizes, resistance osci

Composite-fermion metals occur in the quantum Hall bilayers at total Landau level filling fraction v(T) = 1 as the tunneling gap Delta(SAS) collapses by application of in-plane magnetic fields. Experimental evidence is obtained from the observation o

We observe resonant Rayleigh scattering of light from quantum Hall bilayers at Landau level filling factor nu=1. The effect arises below 1 Kelvin when electrons are in the incompressible quantum Hall phase with strong interlayer correlations. Marked

We report inelastic light scattering measurements of spin excitations on coupled electron bilayers with relatively large tunneling gaps at total filling factor nu(T) = 1. We show that the pseudospin polarization order parameter, where the pseudospin
