We discuss generalizations of quantum spin Hamiltonians using anyonic degrees of freedom. The simplest model for interacting anyons energetically favors neighboring anyons to fuse into the trivial ("identity") channel, similar to the quantum Heisenberg model favoring neighboring spins to form spin singlets. Numerical simulations of a chain of Fibonacci anyons show that the model is critical with a dynamical critical exponent z=1, and described by a two-dimensional (2D) conformal field theory… Expand
Two-dimensional quantum liquids from interacting non-Abelian anyons
A set of localized, non-Abelian anyons?such as vortices in a px+ipy superconductor or quasiholes in certain quantum Hall states?gives rise to a macroscopic degeneracy. Such a degeneracy is split inExpand
Ashkin–Teller universality in a quantum double model of Ising anyons
We study a quantum double model whose degrees of freedom are Ising anyons. The terms of the Hamiltonian of this system give rise to a competition between single and double topologies. By studying theExpand
Integrability in anyonic quantum spin chains via a composite height model

Nonabelions in the fractional quantum Hall effect
Applications of conformal field theory to the theory of fractional quantum Hall systems are discussed. In particular, Laughlin's wave function and its cousins are interpreted as conformal blocks inExpand

Absence of a metallic phase in random-bond Ising models in two dimensions: applications to disordered superconductors and paired quantum Hall states
When the two-dimensional random-bond Ising model is represented as a noninteracting fermion problem, it has the same symmetries as an ensemble of random matrices known as class D. A nonlinear sigmaExpand

Electron correlation in the second Landau level: a competition between many nearly degenerate quantum phases.
It is observed that electrons in the second Landau level of an extremely high-mobility two-dimensional electron system exhibit a very complex electronic behavior and a developing plateau at nu=2+3/8 points to the existence of other even-denominator states. Expand
