Abstract

Through a theoretical coupled wire model, we construct strongly correlated electronic \emph{integer} quantum Hall states. As a distinguishing feature, these states support electric and thermal Hall transport violating the Wiedemann-Franz law as (κxy/σxy)/[(π2kB2T)/3e2]<1\left(\kappa_{xy}/\sigma_{xy}\right)/\left[\left(\pi^{2}k_{B}^{2}T\right)/3e^{2}\right]<1.We propose a new Abelian incompressible fluid at filling ν=16\nu=16 that supports a bosonic chiral (E8)1(E_{8})_{1} conformal field theory at the edge and is intimately related to topological paramagnets in (3+1)D. We further show that this topological phase can be partitioned into two non-Abelian quantum Hall states at filling ν=8\nu=8, each carrying bosonic chiral (G2)1(G_{2})_{1} or (F4)1(F_{4})_{1} edge theories, and hosting Fibonacci anyonic excitations in the bulk. Finally, we discover a new notion of particle-hole conjugation based on the E8E_{8} state that relates the G2G_{2} and F4F_{4} Fibonacci states.
