Two- dimensional topological quantum chemistry and catalog of topological materials Urko Petralanda1,2†*, Yi Jiang3†, Hanqi Pi3, Maia G. Vergniory3,4,5, B. Andrei Bernevig6,3,7*, Nicolas Regnault8,6,9*, Luis Elcoro2* two- dimensional (2D) topological materials host symmetryprotected, disorder- robust edge states central to quantum technologies. Yet they remain scarce compared with their 3D counterparts. We adapted the topological quantum chemistry formalism to layer groups and studied the band topology of 8872 entries from the computational materials databases C2Db and mC2D. We found 4073 topological or obstructed entries, including 905 topological insulators and 1003 obstructed atomic insulators, greatly expanding the library of such materials in two dimensions. …
