This is just one reason why topological insulators are one of ... cross over twice (or an even number of times), the 2D surface states form a pair of Dirac cones (Fig. 2c) — this is similar ...

Unlike conventional insulators that have a bulk bandgap that completely blocks the flow of electrical current, topological insulators have a bulk bandgap that is insulating while also having metallic ...

the presence of Dirac points is crucial for the emergence of their unique topological properties. Specifically, the linear dispersion around Dirac points underpins the formation of robust surface ...

Our research group fabricates and studies colloidal particles with different numbers of handles and genus g. When introduced into a nematic liquid crystal, these particles induce three-dimensional ...

The study of topological states of matter, and their HOT counterparts ... materials that conduct electricity only on the surface or edges, while their interiors remain insulating.

Topological systems are based on ... that emerges as the result of the correlated states of many interacting particles at the ...
