Topological defects and SUSY RG flow

Journal of High Energy Physics, 2021
We study the effect of bulk perturbations of N=(2) superconformal minimal models on topological defects. In particular, symmetries and more general topological defects which survive the flow to the IR are identified.

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.

Codimension-2 defects and higher symmetries in (3+1)D topological phases

SciPost Physics, 2023
(3+1)D topological phases of matter can host a broad class of non-trivial topological defects of codimension-1, 2, and 3, of which the well-known point charges and flux loops are special cases.

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.

Quasi-one-dimensional metallic conduction channels in exotic ferroelectric topological defects

Nature Communications, 2021
Ferroelectric topological defects show emerging exotic physical properties, which are important for future nanoelectronic devices. Here, the authors demonstrate conductive metallic conduction channels in two types of topological defects, namely vortex ...

Non-invertible higher-categorical symmetries

SciPost Physics, 2023
We sketch a procedure to capture general non-invertible symmetries of a $d$-dimensional quantum field theory in the data of a higher-category, which captures the local properties of topological defects associated to the symmetries.
