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…
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…
Spin-ordering and magnon collective modes for two-dimensional electron lattices in strong magnetic fields
R. Cote, A. H. MacDonald
We study the spin-ordering and the magnon collective modes of the two-dimensional Wigner crystal state at strong magnetic fields. Our work is based on the Hartree-Fock approximatio…
Mixed-State Quasiparticle Spectrum for d-wave Superconductors
Yong Wang, A. H. MacDonald
Controversy concerning the pairing symmetry of high- materials has motivated an interest in those measurable properties of superconductors for which qualitative differences ex…
