Spin fractionalization at the edge of quantum Hall fluids induced by bulk quasiparticles
Alexander Fagerlund, Alberto Nardin, Leonardo Mazza +1
We define a measurable spin for the edge of a lowest Landau level and incompressible fractional quantum Hall state in the presence of an Abelian or non-Abelian bulk quasiparticle.…
On the non-hermitian Kitaev chain
Eddy Ardonne, Viktor Kurasov
We study the non-hermitian Kitaev chain model, for arbitrary complex parameters. In particular, we give a concise characterisation of the curves of eigenvalues in the complex plane…
On the unitarity and modularity of ribbon tensor categories associated with affine Lie algebras
Daria Rudneva, Eddy Ardonne
We study the unitarity and modularity of ribbon tensor categories derived from simple affine Lie algebras, via their associated quantum groups. Based on numerical calculations, and…
A bosonic matrix product state description of Read-Rezayi states and its application to quasi-hole spins
Alexander Fagerlund, Eddy Ardonne
We study the Read-Rezayi quantum Hall state by means of a purely bosonic matrix product state formulation, which is described in detail. We calculate the density profiles in…
