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.…

Hierarchy wave functions--from conformal correlators to Tao-Thouless states
E. J. Bergholtz, T. H. Hansson, M. Hermanns +2
Laughlin's wave functions, describing the fractional quantum Hall effect at filling factors , can be obtained as correlation functions in conformal field theory, and re…
