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…
Anyons on Higher Genus Surfaces - a Constructive Approach
T. H. Hansson, Anders Karlhede, Erik Westerberg
We reconsider the problem of anyons on higher genus surfaces by embedding them in three dimensional space. From a concrete realization based on three dimensional flux tubes bound t…
