Global topological k-defects [PDF]

, 2006
We consider global topological defects in symmetry breaking models with a non-canonical kinetic term. Apart from a mass parameter entering the potential, one additional dimensional parameter arises in such models -- a ``kinetic'' mass.

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.

Entanglement entropy in integrable field theories with line defects. Part I. Topological defect

Journal of High Energy Physics, 2017
In this paper and a companion one [1], we study the effect of integrable line defects on entanglement entropy in massive integrable field theories in 1+1 dimensions. The current paper focuses on topological defects that are purely transmissive. Using the

Defects in the 3-dimensional toric code model form a braided fusion 2-category

Journal of High Energy Physics, 2020
It was well known that there are e-particles and m-strings in the 3-dimensional (spatial dimension) toric code model, which realizes the 3-dimensional ℤ2 topological order.

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.

Floquet-engineering of nodal rings and nodal spheres and their characterization using the quantum metric

Physical Review Research, 2020
Semimetals exhibiting nodal lines or nodal surfaces represent a novel class of topological states of matter. While conventional Weyl semimetals exhibit momentum-space Dirac monopoles, these more exotic semimetals can feature unusual topological defects ...

Colloquium : disclination loops, point defects, and all that in nematic liquid crystals [PDF]

, 2012
The homotopy theory of topological defects is a powerful tool for organizing and unifying many ideas across a broad range of physical systems. Recently, experimental progress was made in controlling and measuring colloidal inclusions in liquid ...

A new topological aspect of the arbitrary dimensional topological defects

, 1999
We present a new generalized topological current in terms of the order parameter field $\vec \phi$ to describe the arbitrary dimensional topological defects.

Topological Defects and Gapless Modes in Insulators and Superconductors [PDF]

, 2010
We develop a unified framework to classify topological defects in insulators and superconductors described by spatially modulated Bloch and Bogoliubov de Gennes Hamiltonians.
