Understanding insulators with conducting edges

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists at Goethe University have now modelled ...

A novel topological insulator

For the first time, physicists have built a unique topological insulator in which optical and electronic excitations hybridize and flow together. They report their discovery in Nature.

Disorder induces topological Anderson insulator

Topological insulators (TIs) host exotic physics that could shed new light on the fundamental laws of nature. What's more, the unusual properties of TIs hold tremendous promise for technological applications, including in ...

Modified superconductor synapse reveals exotic electron behavior

Electrons tend to avoid one another as they go about their business carrying current. But certain devices, cooled to near zero temperature, can coax these loner particles out of their shells. In extreme cases, electrons will ...

Bismuth shows novel conducting properties

A team of international scientists including Maia G. Vergniory, Ikerbasque researcher at DIPC and UPV/EHU associate, has discovered a new class of materials, higher-order topological insulators. Theoretical physicists first ...
