It has recently been realized that a general class of non-Abelian defects can be created in conventional topological states by introducing extrinsic defects, such as lattice dislocations or superconductor-ferromagnet domain walls in conventional quantum Hall states or topological insulators. In this paper, we begin by placing these defects within the broader conceptual scheme of extrinsic twist defects associated with symmetries of the topological state. We explicitly study several classes of… Expand

Exotic Non-Abelian Topological Defects in Lattice Fractional Quantum Hall States.
TLDR
The results indicate that genons could be created in the laboratory by combining the physics of artificial gauge fields in cold atom systems with already existing holographic beam shaping methods for creating twist defects, a "proof of concept" demonstration thatgenons do exist in realistic microscopic models.

Theory of defects in Abelian topological states
The structure of extrinsic defects in topologically ordered states of matter is host to a rich set of universal physics. Extrinsic defects in 2+1 dimensional topological states include line-like… Expand
Layer construction of 3D topological states and string braiding statistics
While the topological order in two dimensions has been studied extensively since the discover of the integer and fractional quantum Hall systems, topological states in 3 spatial dimensions are much… Expand
Defects between gapped boundaries in two-dimensional topological phases of matter
Defects between gapped boundaries provide a possible physical realization of projective non-Abelian braid statistics. A notable example is the projective Majorana/parafermion braid statistics of… Expand
Changing topology by topological defects in three-dimensional topologically ordered phases
A hallmark feature of topologically ordered states of matter is the dependence of ground-state degeneracy (GSD) on the topology of the manifold determined by the global shape of the system. Although… Expand
Geometric defects in quantum Hall states
We describe a geometric (or gravitational) analogue of the Laughlin quasiholes in the fractional quantum Hall states. Analogously to the quasiholes these defects can be constructed by an insertion of… Expand
Symmetry fractionalization, defects, and gauging of topological phases
We examine the interplay of symmetry and topological order in $2+1$ dimensional topological phases of matter. We present a definition of the topological symmetry group, which characterizes the… Expand
Theory of Twist Liquids: Gauging an Anyonic Symmetry
Topological phases in (2+1)-dimensions are frequently equipped with global symmetries, like conjugation, bilayer or electric-magnetic duality, that relabel anyons without affecting the topological… Expand
Symmetry fractionalization and twist defects
Topological order in two dimensions can be described in terms of deconfined quasiparticle excitations - anyons - and their braiding statistics. However, it has recently been realized that this data… Expand
Topological phases in two-dimensional arrays of parafermionic zero modes
