Topological phenomena at topological defects

, 2022
There are two prominent applications of the mathematical concept of topology to the physics of materials: band topology, which classifies different topological insulators and semimetals, and topological defects that represent immutable deviations of a solid lattice from its ideal crystalline form.

Topological defects in K3 sigma models [PDF]

Journal of High Energy Physics
We consider the topological defect lines commuting with the spectral flow and the N $$ \mathcal{N} $$ = (4, 4) superconformal symmetry in two dimensional non-linear sigma models on K3.

Orbifolds and Topological Defects [PDF]

Communications in Mathematical Physics, 2014
We study orbifolds of two-dimensional topological field theories using defects. If the TFT arises as the twist of a superconformal field theory, we recover results on the Neveu-Schwarz and Ramond sectors of the orbifold theory as well as bulk-boundary correlators from a novel, universal perspective.

Topological defect lasers [PDF]

Journal of Optics, 2015
We demonstrate topological defect lasers in a GaAs membrane with embedded InAs quantum dots. By introducing a disclination to a square-lattice of elliptical air holes, we obtain spatially confined optical resonances with high quality factor. Such resonances support powerflow vortices, and lase upon optical excitation of quantum dots, embedded in the ...

Topological defects strengthened nonradical oxidation performance of biochar catalyzed peroxydisulfate system

Biochar, 2023
Nonradical oxidation based on peroxydisulfate (PDS) activation has attracted increasing attention for selective degradation of organic pollutants. Herein, topological defects were introduced into biochar (BC) via removing N atoms in N-doped BC (NBC) in ...

Poisson-Lie T-duality defects and target space fusion

Journal of High Energy Physics, 2022
Topological defects have long been known to encode symmetries and dualities between physical systems. In the context of string theory, defects have been intensively studied at the level of the worldsheet.
