Hartree-Fock Theory of Skyrmions in Quantum Hall Ferromagnets
H. A. Fertig, L. Brey, R. Cote +3
We report on a study of the charged-skyrmion or spin-texture excitations which occur in quantum Hall ferromagnets near odd Landau level filling factors. Particle-hole symmetry is u…

A Non-linear Sigma-model for Partially Polarized QH-states
T. H. Hansson, A. Karlhede, J. M. Leinaas
We consider a two-component quantum Hall system within a Landau-Ginzburg theory with two Chern-Simons gauge fields. From this theory we derive a sigma model covariantly coupled to…

Textured Edges in Quantum Hall Systems
A. Karlhede, S. A. Kivelson, K. Lejnell +1
We have investigated the formation of spin textures at the edges of quantum Hall systems for several ferromagnetic filling factors. The textures are driven by the same physics that…
