Knotting semimetals in topological electrical circuits

Invented more than 15,000 years ago, knots represent one of the earliest technological breakthroughs at the dawn of human history that kick-started the subsequent rise of human civilisation. Even today, we are still relying ...

First confirmation of new theory by metamaterial

Topological metamaterials are applied as a novel platform to explore and study extraordinary effects. Instead of using natural materials, researchers artificially arrange the constituents of a topological metamaterial in ...
