Observability of counterpropagating modes at fractional-quantum-Hall edges
U. Zuelicke, A. H. MacDonald, M. D. Johnson
When the bulk filling factor is equal to 1 - 1/m with m odd, at least one counterpropagating chiral collective mode occurs simultaneously with magnetoplasmons at the edge of fracti…
Integer quantum Hall effect for hard-core bosons and a failure of bosonic Chern-Simons mean-field theories for electrons at half-filled Landau level
O. Heinonen, M. D. Johnson
Field-theoretical methods have been shown to be useful in constructing simple effective theories for two-dimensional (2D) systems. These effective theories are usually studied by p…
Ensemble density functional theory of the fractional quantum Hall effect
O. Heinonen, M. I. Lubin, M. D. Johnson
We develop an ensemble density functional theory for the fractional quantum Hall effect using a local density approximation. Model calculations for edge reconstructions of a spin-p…
Nonlinear Steady-State Mesoscopic Transport, I. Formalism
M. D. Johnson, O. Heinonen
We present an approach to steady-state mesoscopic transport based on the maximum entropy principle formulation of nonequilibrium statistical mechanics. This approach is valid in th…
Haldane fractional statistics in the fractional quantum Hall effect
M. D. Johnson, G. S. Canright
We have tested Haldane's ``fractional-Pauli-principle'' description of excitations around the state in the FQHE, using exact results for small systems of electrons. We fin…
