Is it topological? A new materials database has the answer
May 2022, phys.org
Topo is coming:
Harnessing the power of multiple supercomputers to map the electronic structure of more than 96,000 natural and synthetic crystalline materials to determine whether and what kind of topological traits exist in each structure.Overall, they found that 90 percent of all known crystalline structures contain at least one topological property, and more than 50 percent of all naturally occurring materials exhibit some sort of topological behavior.
Topological Materials Database - periodic table of topology
Inorganic Crystal Structure Database - atomic and chemical structures of crystalline materials
