Fig. 1: GC cases with 1 fine-tuning parameter.

From: Piezoelectricity and topological quantum phase transitions in two-dimensional spin-orbit coupled crystals with time-reversal symmetry

Fig. 1

The figure shows the GC cases between insulating states with 1 fine-tuning parameter for all 7 PGs with non-vanishing PET. The red cross labels the GC momenta, the light blue background indicates the 1BZ, and the light red part in a indicates the half 1BZ. The black and orange dashed lines label the momenta invariant under the mirror/glide symmetry and the combination of mirror/glide and TR symmetries, respectively. The figures are first grouped according to the PGs and then ordered based on the GC scenarios listed in Table 1, whose labels are next to the names of the PGs.
