Topological insulators are materials that are insulating in their interior but can support the flow of electrons on their surface. The underlying cause is time-reversal symmetry: their physics is ...
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 ...
Definition: Topological materials are a class of substances that exhibit unique properties due to their distinct electronic structure, which is governed by topology rather than the conventional order ...
