Electronic correlation in the quantum Hall regime
Marcus Kasner
Two-dimensional interacting electron systems become strongly correlated if the electrons are subject to a perpendicular high magnetic field. After introducing the physics of the qu…
Itinerant Electron Ferromagnetism in the Quantum Hall Regime
Marcus Kasner, J. J. Palacios, A. H. MacDonald
We report on a study of the temperature and Zeeman-coupling-strength dependence of the one-particle Green's function of a two-dimensional (2D) electron gas at Landau level filling…
Shadow Bands and Tunneling Magnetoresistance in Itinerant Electron Ferromagnets
A. H. MacDonald, T. Jungwirth, M. Kasner
In itinerant electron ferromagnets spectral weight is transferred at finite temperatures from quasiparticle peaks located at majority and minority-spin band energies to shadow-band…
Thermodynamics of Quantum Hall Ferromagnets
Marcus Kasner, A. H. MacDonald
The two-dimensional interacting electron gas at Landau level filling factor and temperature is a strong ferromagnet; all spins are completely aligned by arbitrarily wea…
Electrons in a Strong Magnetic Field on a Disk
M. Kasner, W. Apel
The problem of interacting electrons moving under the influence of a strong magnetic field in two dimensions on a finite disk is reconsidered. First, the results of exact diagonali…
Test of the hierarchical theory for the FQHE
M. Kasner
In the hierarchical theory of the fractional quantum Hall effect, the low--energy behaviour of a daughter state in the next level of the hierarchy is described by an interacting sy…
