WebJan 27, 2024 · The irreducible representation of band structure is important for physical properties. Based on phonopy and recently developed SpaceGroupIrep package, we developed a package PhononIrep, which can get the band irreducible representation for arbitrary point at first-principles level. WebMar 1, 2024 · IrRepis a Python code for the calculation of irreducible representations of DFT calculated bands at high-symmetry points. It is a powerful tool for the detection and classification of topological sets of bands and materials, applicable with calculations performed both with or without SOC and using unit cells that might be non-conventional.
