Bicategories for boundary conditions and for surface defects in 3-d TFT

, 2013
We analyze topological boundary conditions and topological surface defects in three-dimensional topological field theories of Reshetikhin-Turaev type based on arbitrary modular tensor categories. Boundary conditions are described by central functors that

Topological defects and shape of aromatic self-assembled vesicles [PDF]

, 2009
We show that the stacking of flat aromatic molecules on a curved surface results in topological defects. We consider, as an example, spherical vesicles, self-assembled from molecules with 5- and 6-thiophene cores.

Aspects of categorical symmetries from branes: SymTFTs and generalized charges

SciPost Physics
Recently it has been observed that branes in geometric engineering and holography have a striking connection with generalized global symmetries. In this paper we argue that branes, in a certain topological limit, not only furnish the symmetry generators,

Annihilation of Highly-Charged Topological Defects

Crystals, 2020
We studied numerically external stimuli enforced annihilation of a pair of daughter nematic topological defect (TD) assemblies bearing a relatively strong topological charge |m|=3/2.

Topological current of point defects and its bifurcation

, 1999
From the topological properties of a three dimensional vector order parameter, the topological current of point defects is obtained. One shows that the charge of point defects is determined by Hopf indices and Brouwer degrees.

Topological manipulations on ℝ symmetries of Abelian gauge theory

Journal of High Energy Physics
Performing topological manipulations is a fruitful way to understand global aspects of Quantum Field Theory (QFT). Such modifications are typically controlled by the notion of Topological QFT (TQFT) coupling across different codimensions.

A unified field theory of topological defects and non-linear local excitations

npj Computational Materials, 2023
Topological defects and smooth excitations determine the properties of systems showing collective order. We introduce a generic non-singular field theory that comprehensively describes defects and excitations in systems with O(n) broken rotational ...

Defects in vibrated monolayers of equilateral triangular prisms

Physical Review Research
We present experimental results in which a quasimonolayer of grains, shaped as equilateral triangular prisms, is vertically vibrated within circular and square confining cavities.

Phase synchronization and topological defects in inhomogeneous media [PDF]

, 2002
The influence of topological defects on phase synchronization and phase coherence in two-dimensional arrays of locally-coupled, nonidentical, chaotic oscillators is investigated.
