New topological materials could have multiple electrical properties

This it is the story of a unique material—made of a single compound, it conducts electrons in different ways on its different surfaces and doesn't conduct at all in its middle. It is also the story of three research groups—two ...

Cherned up to the maximum

In topological materials, electrons can display behavior that is fundamentally differentfrom that in 'conventional' matter, and the magnitude of many such 'exotic' phenomena is directly proportional to an entity known as ...

A fresh twist in chiral topology

The concept of chirality is well-established in science: when an object cannot be superimposed on its mirror image, both the object and its mirror image are called chiral. In the drug industry, for instance, more than 50% ...
