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 ...

Topological insulators are a relatively new type of quantum material that has insulating properties on the inside, but have conductive properties on the outside. To use a Southern California ...

Experiment has now proved the existence of the predicted three-dimensional 'topological insulator' in the semiconducting alloy Bi 1−x Sb x. One of the triumphs of quantum mechanics in the ...

He Qinglin's group at the Center for Quantum Materials Science, School of Physics, has reported the first observation of ...

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 ...

In the study, the team presented a novel 3D higher-order topological insulator (HOTI) exhibiting an octupole insulating phase within the framework of the Brillouin 3D real projective space.

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 ...

Chern insulators are magnetic topological materials that show a quantized Hall effect without external magnetic fields, due to intrinsic magnetization and chiral edge states. (i)Makes the first ...

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

A groundbreaking study led by researchers from Southeast University, the Chinese Academy of Sciences, the University of Hong Kong, and the University ...
