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 ...

Higher-order topological insulators (HOTIs) are unique materials hosting topologically protected states, whose dimensionality is at least by 2 lower than that of the bulk. Topological states in such ...

Three-dimensional all-dielectric photonic topological insulators are experimentally shown to control far-field emission via the pseudo-spin degree of freedom. To understand the importance of this, one ...

Magnetic quantum oscillations have been unexpectedly observed in insulators, where freely moving charge carriers are not ...

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 ...

Topological insulators are regarded as the key to novel 'spintronic' devices and quantum computers of the future due to their unique electronic properties. Physicists have now been able to understand ...

Scientists have long dreamed of making molecular electronics, building one-dimensional strings atom by atom to create new circuits even smaller than today’s tiniest silicon structures. Shrinking ...

(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 ...

All materials do not conduct electricity in the same way. This difference depends on the behavior of the electrons that ...

In the present era of modern nano-technologies, controlling light at the smallest scales is the key to faster communications, ultra-sensitive sensors, and revolutionary imaging systems. This is where ...

(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 ...

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 ...
