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.

Topological defects in Floquet circuits

SciPost Physics
We introduce a Floquet circuit describing the driven Ising chain with topological defects. The corresponding gates include a defect that flips spins as well as the duality defect that explicitly implements the Kramers-Wannier duality transformation.

Complementary projection defects and decomposition

Journal of High Energy Physics, 2021
As put forward in [1] topological quantum field theories can be projected using so-called projection defects. The projected theory and its correlation functions can be completely realized within the unprojected one.

Effects of Topological Defects and Magnetic Flux on Dissociation Energy of Quarkonium in an Anisotropic Plasma

East European Journal of Physics
In this paper, we investigate the effects of anisotropic parameters, topological defects, and magnetic flux on the dissociation energy of bottomonium in an anisotropic quark-gluon plasma.

Topological Defect Evolutions Guided by Varying the Initial Azimuthal Orientation

Applied Sciences
Topological defects are a key concern in numerous branches of physics. It is meaningful to exploit the topological defect evolutions during the phase transitions of condensed matter.

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.

Clifford Algebras and Liquid Crystalline Fermions

Physical Review X
We 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 ...
