Non-abelian quantum hall states - Exclusion statistics, K-matrices, and duality

We study excitations in edge theories for non-abelian quantum Hall states. focussing on the spin polarized slates proposed by Read and Rezayi and on t he spill singlet states proposed by two of the authors. By studying the exc lusion statistics properties of edge-electrons and edge-quasiholes, we arri ve at a novel K-matrix structure. Interestingly, the duality between the el ectron and quasihole sectors links the pseudoparticles that are characteris tic for non-abelian statistics with composite particles that are associated to the "pairing physics" of the non-abelian quantum Hall states.
