Soft-Matter Physics Provides New Insights on Myocardial Architecture: Automatic and Quantitative Identification of Topological Defects in the Trabecular Myocardium [PDF]

Journal of Cardiovascular Development and Disease, 2023
This article is the third in our series dedicated to the analysis of cardiac myoarchitecture as a nematic chiral liquid crystal (NCLC). Previously, we introduced the concept of topological defects (disclinations) and focused on their visual ...

Experimental identification of topological defects in 2D colloidal glass [PDF]

Nature Communications
Topological defects are singularities within a field that cannot be removed by continuous transformations. The definition of these irregularities requires an ordered reference configuration, calling into question whether they exist in disordered ...

Hedgehog topological defects in 3D amorphous solids [PDF]

Nature Communications
The underlying structural disorder renders the concept of topological defects in amorphous solids difficult to apply and hinders a first-principle identification of the microscopic carriers of plasticity and of regions prone to structural rearrangements (

Curvature-Controlled Topological Defects [PDF]

Crystals, 2017
Effectively, two-dimensional (2D) closed films exhibiting in-plane orientational ordering (ordered shells) might be instrumental for the realization of scaled crystals. In them, ordered shells are expected to play the role of atoms.

On the geometry of topological defects in glasses. [PDF]

Nat Commun
Abstract Recent studies have revealed a series of connections between the topological features of structural glasses and their material properties. These findings bear a striking resemblance to results observed in quantum physics, underscoring the significance of the nature of the wavefunction.

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.

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.
