List of fragile roots in the 230 space groups

The file FragileRoots.tar.gz contains the fragile roots of the 230 space groups when Spin-Orbit Coupling is considered (double-valued representations). Once the file is decompressed, there is a single file for each space group with fragile roots. The fragile roots are given (one root in each row of the file) by the multiplicities of the irreducible representations at the maximal k-vectors of the group, in a specific order of the irreps. The chosen order of irreps in each space group are included in the file DoubleIrrepsSG.tar.gz. If you are using these lists in the preparation of an article, please cite the two references below, where you can get more information about the calculation, use and mean of the data in the files. k-Subgroupsmag
