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 ...

The discovery of a dual topological insulator introduces a new method for creating topological flat minibands through electron interactions, which offer a promising platform for exploring exotic ...

and thereby controlled the frequency of topological charge sign flips of quantized vortices in polariton condensates. To ...

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 ...
