In amorphous systems such as glasses, or a random network of neuronal connections, topological defects were observed for the first time in numerical simulations only in 2021, thanks to computer ...

In the vast universe, galaxies rotate in ways that don’t make sense if only visible matter is considered. For almost a ...

Topological defects are quasiparticles whose topological nature provides some stability against perturbations. Skyrmions, domain walls, dislocations in crystals, vortices in superconductors and ...

Defects are responsible for many well-known processes: plastic deformations and fracture in metals are governed by dislocations, vortices in the atmosphere show up as tornadoes, disclinations in ...

Majorana qubits could be error resistant. But after a contentious talk at the Global Physics Summit, scientists aren’t convinced Microsoft has them.

But a MZM exists in a vortex, a tornado-like swirl of electrons in the topological defects of a superconducting material. Research to date has insisted that such vortices can only be generated by ...

When introduced into a nematic liquid crystal, these particles induce three-dimensional director fields and topological defects dictated by colloidal topology. While electric fields, photothermal ...

1). However, due to bundle extensility, the uniform nematic state is unstable to the formation of topological defect pairs (Fig. 2). Defect pairs spontaneously appear, unbind, move through the sample, ...

This means that charged particles can flow freely on their edges and route themselves around defects but can't pass through their interiors. The electrical properties of these substances result from ...

Instead of invisible matter, Lieu believes the extra gravity may be coming from structures in space known as topological defects. Topological defects are regions in the universe where the ...
