Topological lattice defects in topological materials offer a platform to explore a diverse range of phenomena, including fractional charges, chiral and gravitational anomalies, topological lasers and non-Hermitian skin effects. This Perspective article surveys the impact of these phenomena on condensed matter physics, photonics, acoustics and materials science.
