15 years of topological matter

15 years ago, topological insulators were discovered, marking the start of a new branch of condensed matter physics. Soon, topological behaviour was discovered in many different systems, including topological semimetals, superconductors and magnets. Studying these topological materials has led to advances in our understanding of physics, as well as in practical achievements towards devices and applications. In this Collection, we bring together a selection of articles to show where the field is today.
