Topological insulators (TIs) are among the hottest topics in condensed matter physics today. They're a bit strange: Their ...

Topological insulators are materials that are insulating ... These surface states are robust, maintained even in the presence of surface defects. Periodic laser light can modify the electronic ...

When these constraints cannot be respected at some peculiar intersection points, nanometric topological defects are formed. "Indeed, it is at these specific points that the insulator-to-metal ...
