Topological defects as Lagrangian correspondences

Physical Review D, 2023
Topological defects attract much recent interest in high-energy and condensed matter physics because they encode (non-invertible) symmetries and dualities. We study codimension-1 topological defects from a hamiltonian point of view, with the defect location playing the role of `time'.

Topological defects from the multiverse [PDF]

Journal of Cosmology and Astroparticle Physics, 2015
Many theories of the early universe predict the existence of a multiverse where bubbles continuously nucleate giving rise to observers in their interior. In this paper, we point out that topological defects of several dimensionalities will also be produced in de Sitter like regions of the multiverse.

TOPOLOGICAL DEFECTS AND STRUCTURE FORMATION [PDF]

International Journal of Modern Physics A, 1994
Topological defects are produced during phase transitions in the very early Universe. They arise in most unified theories of strong, weak and electromagnetic interactions. This article focuses on the role of topological defects in cosmology, with particular emphasis on the models of structure formation based on defects. The role of topological defects

Topological defects for the free boson CFT

, 2007
Two different conformal field theories can be joined together along a defect line. We study such defects for the case where the conformal field theories on either side are single free bosons compactified on a circle. We concentrate on topological defects

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.

Signatures of Topological Defects in the Microwave Sky: An Introduction [PDF]

, 1997
An introduction to topological defects in cosmology is given. We discuss their possible relevance for structure formation. Especial emphasis is given on the signature of topological defects in the spectrum of anisotropies in the cosmic microwave ...

Role of topological defects in the phase transition of modified XY model : A Monte Carlo study

, 2010
Monte Carlo simulation has been performed on a classical two dimensional XY- model with a modified form of interaction potential to investigate the role of topological defects on the phase transition exhibited by the model. In simulations in a restricted

Topological defects and topological materials

Integrated Ferroelectrics, 2016
ABSTRACTDefects in materials that interpolate between two orientation states such as domain walls and those which relate to some kind of material discontinuity, e.g. dislocations and disclinations, comprise topological defects. Noncoplanar vector arrangements, e.g.

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.
