ARPES maps the electronic properties, including the band structure and Fermi surface, of the topological insulator bismuth selenide (left). Like graphene, the lower energy valence band of a ...

The electron world, where electrons (dwarfs) explore their energy band (beach), can be manipulated using external fields or light in strongly correlated insulators. This ability enables new electronic ...

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 ...

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 ...
