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 ...

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 ...

(a) Schematic of Te crystal which is formed by hexagonal arrangement of Te helix chains. (b) Single Te helix chain with boundary charge. A joint research team that included members from Tohoku ...

Physicists at the University of Cologne have taken an important step forward in the pursuit of topological quantum computing by demonstrating the first-ever observation of Crossed Andreev Reflection ...

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 ...

Intriguing effects can arise in materials that have electrons with unusual ‘band structures’. “Electrons behave as waves in solids, and the relationship between their energy and momentum is described ...

A new fusion of materials, each with special electrical properties, has all the components required for a unique type of superconductivity that could provide the basis for more robust quantum ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

(Nanowerk News) A joint research team has unveiled a new topological insulator (TI), a unique state of matter that differs from conventional metals, insulators, and semiconductors. Unlike most known ...
