Topological matter refers to systems in which topology is required for their characterisation. This includes materials with topological defects such as skyrmions, or topologically-protected edge ...

Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They’re a bit strange: their surfaces conduct electricity, yet their interiors do not, instead acting as ...

Topological insulators are strange stuff – the bulk of this material is insulating and cannot carry an electrical current, yet the surfaces of the same material are conducting. This means that charged ...

I personally believe that the experimental demonstration of the existence of topological defects in disordered systems is a turning point in condensed matter physics because it paves the way for ...

By twisting layers of graphene, researchers discovered a unique electronic crystal where electrons freeze in place yet allow ...

"Topological effects are very compact regions of space with a very high density of matter, usually in the form of linear ...

“Several theory groups have speculated that analogues of these structures could emerge in quantized anomalous Hall systems, ...

Thin conductor: A chip made of the non-crystalline topological semimetal niobium phosphide. (Courtesy: A Khan) Metals usually become less conductive as they get thinner. Niobium phosphide, however, is ...

These devices have proved to be promising platforms for the exploration of topological phenomena in condensed matter physics. Researchers at Northwestern University and Aalto University recently ...
