Fractional domain walls from on-site softening in dipolar bosons
Emma Wikberg, Jonas Larson, Emil J. Bergholtz +1
We study dipolar bosons in a 1D optical lattice and identify a region in parameter space---strong coupling but relatively weak on-site repulsion---hosting a series of stable charge…
Topological Field Theory for p-wave Superconductors
T. H. Hansson, A. Karlhede, Masatoshi Sato
We propose a topological field theory for a spin-less two-dimensional chiral superconductor that contains fundamental Majorana fields. Due to a fermionic gauge symmetry, the Majora…
Exclusion statistics for quantum Hall states in Tao-Thouless limit
Mikael Kardell, Anders Karlhede
We consider spin-polarized abelian quantum Hall states in the Tao-Thouless limit, {\it ie} on a thin torus. For any filling factor a well-defined sector of low-energy state…
Tao-Thouless Revisited
T. H. Hansson, A. Karlhede
It is now established that the state proposed by Tao and Thouless for the fractional quantum Hall effect in 1983, shortly after Laughlin's work, is the ground state in the so-calle…
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…
