Binding self-propelled topological defects in active turbulence
Physical Review Research, 2020 We report on the emergence of stable self-propelled bound defects in monolayers of active nematics, which form virtual full-integer topological defects in the form of vortices and asters.

Topological defects in a deformed gauge theory
Nuclear Physics B, 2017 In this paper, we will analyse the topological defects in a deformation of a non-abelian gauge theory using the Polyakov variables. The gauge theory will be deformed by the existence of a minimum measurable length scale in the background spacetime.

Clifford Algebras and Liquid Crystalline Fermions
Physical Review XWe show that Clifford algebras provide a natural language to describe the physics of liquid crystal defects in 3D. This framework shows that most of these defects have fermionic nature, as the director field profile on a 2D cross section can ...

Probing topological protection using a designer surface plasmon structure
Nature Communications, 2016 The limits of topological protection in photonic systems remain unclear. Here, Gao et al. construct photonic topological edge states and probe their robustness against a variety of defect classes, including some common time-reversal-invariant photonic ...

Three dimensional magnetic solutions in massive gravity with (non)linear field
Physics Letters B, 2017 The Noble Prize in physics 2016 motivates one to study different aspects of topological properties and topological defects as their related objects. Considering the significant role of the topological defects (especially magnetic strings) in cosmology ...

Topological defects and tensionless holography
Journal of High Energy PhysicsWe study topological defect lines in the symmetric-product orbifolds Sym N (X) for a generic seed CFT X. We focus on the defects which preserve the maximum of the S N symmetry.

Topological Large-Area Waveguide States Based on THz Photonic Crystals
PhotonicsTerahertz (THz) has attracted substantial attention owing to its unique advantages in high-speed communications. However, conventional THz waveguide systems are inherently constrained by high transmission losses, stringent fabrication precision ...

, 1999 We address some issues of topological defect inflation. (1) We clarify the causal structure of an inflating magnetic monopole. The spacetime diagram shows explicitly that this model is free from the ``graceful exit'' problem, while the monopole itself undergoes ``eternal inflation''.
