Sensing the binding and unbinding of anyons at impurities

Physical Review Research
Anyons are quasiparticles with fractional charge and statistics that arise in strongly correlated two-dimensional systems such as the fractional quantum Hall effect and fractional Chern insulators.

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 ...

Anyon condensation and tensor categories

Nuclear Physics B, 2014
Instead of studying anyon condensation in various concrete models, we take a bootstrap approach by considering an abstract situation, in which an anyon condensation happens in a 2-d topological phase with anyonic excitations given by a modular tensor ...

Fractionalizing Majorana Fermions: Non-Abelian Statistics on the Edges of Abelian Quantum Hall States

Physical Review X, 2012
We study the non-Abelian statistics characterizing systems where counterpropagating gapless modes on the edges of fractional quantum Hall states are gapped by proximity coupling to superconductors and ferromagnets. The most transparent example is that of

Non-abelian anyons and logic gates

openIl calcolo quantistico topologico è un nuovo paradigma di calcolo quantistico che utilizza gli anyoni non abeliani sia per codificare gli stati quantistici, sia per implementare le porte logiche in maniera topologica.

Quantum Field Theory of anyons.

, 1988
For a Minkowski spacetime of dimension three, particles of arbitrary, real spin and intermediate (thetav-) statistics, called lsquoanyonsrsquo, are studied within the framework of relativistic quantum field theory.

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.

Anyon condensation in mixed-state topological order

SciPost Physics Core
We discuss anyon condensation in mixed-state topological order. The phases were recently conjectured to be classified by pre-modular fusion categories. Just like anyon condensation in pure-state topological order, a bootstrap analysis shows condensable ...

Anyons in one-dimensional lattices: a photonic realization

, 2012
Anyons are nonlocal quasi-particles carrying fractional statistics that interpolate between bosons and fermions. Here we propose a photonic realization of anyons moving on a one-dimensional lattice, which is based on light transport in an engineered ...

Diagonal Coset Approach to Topological Quantum Computation with Fibonacci Anyons [PDF]

We investigate a promising conformal field theory realization scheme for topological quantum computation based on the Fibonacci anyons, which are believed to be realized as quasiparticle excitations in the $\mathbb{Z}_3$ parafermion fractional quantum ...
