The Topological Materials Database provides a comprehensive catalogue of crystalline compounds classified through Topological Quantum Chemistry (TQC). It hosts more than 38,000 materials, including topological insulators and semimetals, identified via symmetry-based electronic band analysis. The database enables researchers to search, predict, and explore topological properties of materials, offering a unique resource for condensed matter physics and materials science. It is widely used for discovering candidate compounds for quantum technologies and has become a cornerstone reference for the study of topological phases in real materials.
