Topological insulators (TIs) are a class of materials with surfaces that host a new quantum state of matter and are insensitive to contaminants, defects and impurities. Surface electrons in TIs behave ...

Researchers at ETH Zurich have developed a new technique to better understand how electrons interact within materials. By ...

as in conventional insulators, but from their lack of mobility due to repulsive interactions between electrons. Although ...

It hardly conducts any electricity at all, so we can say it’s an electrical insulator. Inside the plastic, all the electrons are tightly bound to the atoms, so the charges cannot move very far ...

Their magnetic components, called spins, change the rules electrons usually follow in conventional TIs by disrupting their surface-conducting abilities, effectively turning TIs into insulators.

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 ...

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 ...
