Funding

Work at the University of Vienna was sponsored by the FWF project INDOX (Grant No. I1490-N19). Work at the Shenyang National Laboratory for Materials Science was supported by the National Science Fund for Distinguished Young Scholars (No. 51725103), by the National Natural Science Foundation of China (Grant Nos. 51671193 and 51474202), and by the Science Challenging Project No. TZ2016004. D.D.S. was supported by the German Research Foundation (DFG- SFB 1170) and acknowledges the ERC-StG-336012-Thomale-TOPOLECTRICS. J.M.R. was supported by the Army Research Office (W911NF-15-1-0017). All calculations were performed on the Vienna Scientific Cluster (VSC) and partially at the high-performance computational cluster in the Shenyang National University Science and Technology Park, as well as the National Supercomputing Center in Guangzhou (TH-2 system).
