When mobile charge carriers, also known as itinerant electrons, interact with the strong exchange magnetic fields associated ...

Artistic illustration of a topological exciton insulator: Excitons condense in the bulk of the material, forming a collective insulating phase, while topologically protected edge modes propagate ...

Topological materials are a class of materials that exhibit unique electronic properties at their boundary (surface in 3D materials; edge in 2D materials) that are robust against imperfections or ...

Heterostructures consisting of magnetic insulator layers (e.g., EuS, YIG) and topological insulator films have also been explored for realizing QAH insulators. The proximity-induced magnetic exchange ...

Just like a book can’t be judged by its cover, a material can’t always be judged by its surface. But, for an elusive conjectured class of materials, physicists have now shown that the surface ...

The candidate pool for engineered materials that can help enable tomorrow's cutting-edge optical technologies—such as lasers, detectors and imaging devices—is much deeper than previously believed.

Topological materials can be categorized into several types, including topological insulators, topological superconductors, and topological semimetals. Each type exhibits unique electronic properties ...

A team of researchers from the Kavli Institute for Theoretical Sciences, China, have developed a new framework for modelling strongly correlated topological insulators A material's band structure can ...

RIKEN physicists have created the first thin films featuring a special combination of electrical and topological properties. This demonstration could help to realize new forms of electronics that are ...
