Spin chain description of rotating bosons at
Emma Wikberg, Emil J. Bergholtz, Anders Karlhede
We consider bosons at Landau level filling on a thin torus. In analogy with previous work on fermions at filling , we map the low-energy sector onto a spin-1/2 chain.…

Quantum Hall Circle
E. J. Bergholtz, A. Karlhede
We consider spin-polarized electrons in a single Landau level on a cylinder as the circumference of the cylinder goes to infinity. This gives a model of interacting electrons on a…
