Internal Excitations and Dissipative Damping of Quantum Hall Skyrmions
H. A. Fertig, L. Brey, R. Cote +1
We propose an intrinsic maximum speed for dissipationless E cross B drift of Skyrmion quasiparticles in quantum Hall ferromagnets. When this speed is exceeded, Skyrmions can radiat…
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…
Collective Modes of Soliton-Lattice States in Double-Quantum-Well Systems
R. Cote, L. Brey, H. Fertig +1
In strong perpendicular magnetic fields double-quantum-well systems can sometimes occur in unusual broken symmetry states which have interwell phase coherence in the absence of int…
Spiral Magnets as Gapless Mott Insulators
R. Cote, A. -M. S. Tremblay
In the large limit, the ground state of the half-filled, nearest-neighbor Hubbard model on the triangular lattice is the three-sublattice antiferromagnet. In sharp contrast wit…
