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 ...

Purdue University doctoral student Yang Xu, lead author of a new research paper on "topological insulators," an emerging class of materials that could make possible "spintronic" devices and practical ...

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 ...

Dual topological phases have been discovered in an intrinsic monolayer crystal, a finding that reveals new and unique rule-bending properties in a quantum material, an international team of scientists ...

Physicists from University of Jyväskylä and Aalto University (Finland) have experimentally realized a two-dimensional topological crystalline insulator. This is a quantum material that has been ...

Science can be difficult to explain to the public. In fact, any subfield of science can be difficult to explain to another scientist who studies in a different area. Explaining a theoretical science ...

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 ...

(Nanowerk News) Topological insulators raise the exciting the hope of realising lossless energy transport, which is true at ultralow temperatures. However, topological insulators fail to maintain this ...

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 ...

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 ...
