Ensemble Density Functional Theory for Inhomogeneous Fractional Quantum Hall Systems
O. Heinonen, M. I. Lubin, M. D. Johnson
The fractional quantum Hall effect (FQHE) occurs at certain magnetic field strengths B*(n) in a two-dimensional electron gas of density n at strong magnetic fields perpendicular to…

Density matrix for a mesoscopic current ribbon
O. Heinonen, M. D. Johnson
We consider an ideal mesoscopic ribbon in which a steady azimuthal current is generated. We show that the closed interacting electron system in the presence of the current is descr…
