Bulk charge distributions on integer and fractional quantum Hall plateaus
J. J. Palacios, A. H. MacDonald
We discuss the charge distributions across the bulk of a two-dimensional electron gas system which is on an integer or fractional quantum Hall plateau. Our analysis is based on a r…
Numerical Tests of the Chiral Luttinger Liquid Theory for Fractional Hall Edges
J. J. Palacios, A. H. MacDonald
We report on microscopic numerical studies which support the chiral Luttinger liquid theory of the fractional Hall edge proposed by Wen. Our calculations are based in part on newly…
Low-lying excitations of Quantum Hall Droplets
J. H. Oaknin, L. Martin-Moreno, J. J. Palacios +1
We present the adequate circular representation of charge density excitations in Quantum Hall droplets at filling factor 1. A novel set of operators describes magnetoexcitons with…
Mode-Matching Technique for Transmission Calculations in Electron Waveguides at High Magnetic Fields
J. J. Palacios, C. Tejedor
In this paper we present a mode-matching technique to study the transmission coefficient of mesoscopic devices such as electron waveguides in the presence of high magnetic fields f…
Phase Separation of Edge States in the Integer Quantum Hall Regime
L. Brey, J. J. Palacios, C. Tejedor
Coulomb effects on the edge states of a two dimensional electron gas in the presence of a high magnetic field are studied for different widths of the boundaries. Schrödinger and Po…
