Chiral edge states emerging on anyon-net

SciPost Physics Core
We propose a symmetry-based approach to constructing lattice models for chiral topological phases, focusing on non-Abelian anyons. Using a 2+1D version of anyon chains and modular tensor categories (MTCs), we ensure exact MTC symmetry at the microscopic ...

A Quantum Impurity Model for Anyons

, 2020
International audienceOne of the hallmarks of quantum statistics, tightly entwined with the concept of topological phases of matter, is the prediction of anyons.

Intrinsic Mixed-State Topological Order

PRX Quantum
Decoherence is a major obstacle to the preparation of topological order in noisy intermediate-scale quantum devices. Here, we show that decoherence can also give rise to new types of topological order.

Quantum entanglement of anyonic charges and emergent spacetime geometry

New Journal of Physics
Intrinsically topologically ordered phases can host anyons. Here, we take the view that entanglement between anyons can give rise to an emergent geometry resembling Anti-de Sitter (AdS) space.

On the torus quantization of two anyons with Coulomb interaction in a magnetic field

, 1997
We study two anyons with Coulomb interaction in a uniform magnetic field B. By using the torus quantization we obtain the modified Landau and Zeeman formulas for the two anyons.

Ground state of many anyons in a harmonic potential

, 1992
The ground-state energy and wave function of many anyons in a harmonic oscillator potential is studied using perturbation theory from the fermionic and bosonic ends.

How Much Entanglement Is Needed for Topological Codes and Mixed States with Anomalous Symmetry?

Physical Review X
It is known that particles with exotic properties can emerge in systems made of simple constituents such as qubits, due to long-range quantum entanglement.

Boson-anyon-fermion mapping and anyon construction in one dimension

Physical Review Research
We establish an exact mapping between identical particles in one dimension with arbitrary exchange statistics, including bosons, anyons, and fermions, provided they share the same scattering length.

Bloch oscillations of Fibonacci anyons [PDF]

Non-Abelian anyons, which correspond to collective excitations possessing multiple fusion channels and noncommuting braiding statistics, serve as the fundamental constituents for topological quantum computation.

Anyons as perturbed bosons

, 1992
We study a system of anyons with the statistics parameter θ=π/p, where p is a large integer. We use a recently developed first-order perturbation expansion about the bosonic limit θ=0, which produces a pairwise repulsive δ-function potential. In addition,
