Electron-phonon interactions on a single-branch quantum Hall edge
O. Heinonen, Sebastian Eggert
We consider the effect of electron-phonon interactions on edge states in quantum Hall systems with a single edge branch. The presence of electron-phonon interactions modifies the s…
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…
Mesoscopic transport beyond linear response
O. Heinonen, M. D. Johnson
We present an approach to steady-state mesoscopic transport based on the maximum entropy principle formulation of nonequilibrium statistical mechanics. Our approach is not limited…
Surface Effects on Bulk Plasmons
Olle Heinonen, Walter Kohn
We discuss the effects of surfaces on bulk plasma oscillations in a metallic film of thickness . The leading corrections to the plasma frequencies due to the surfaces are propor…
