topological order of various materials despite DFT's well-known band-gap underestimation.
Use of the more accurate quasi-particle GW approach reveals few cases where DFT
identifications are false positive, which can possibly misguide experimental searches for
materials that are topological insulators (TIs) in DFT but not expected to be TIs in reality. We
also present the case of false positives due to the incorrect choice of crystal structures and …
