Compatibility of DeePTB-E3 with SOC scenario

[ChenQianA]

Hi, everyone. Since DeepTB (the 1st version) is compatible with SOC cases, I'm a bit curious about the compatibility of DeePTB-E3 (the 2nd version) with SOC scenarios. As in the DeepTB-E3 paper, the benchmarking datasets are all for the noSOC scenario. On the other hand, DeepTB-E3 is based on the SO(2) operation. Theoretically speaking, SO(2) may be a bit tricky regarding numerical stability, even compared to O(3) CGTB, especially when the irrep parities are more complicated when SOC is involved. Has DeepHTB-E3 been tested for SOC scenarios, and is it compatible?
