IRSSG is a new open-source DFT-interfacing package that computes spin space group operations, compact international symbols, character tables, and irreducible corepresentation labels for magnetic bands.
Relativistic altermagnets exhibit mixed g-, d-, and p-wave spin-momentum locking with symmetry-protected nodal planes and accidental nodal surfaces depending on Néel vector orientation.
Polar distortions induced by surface symmetry breaking or electric fields substantially modify the anomalous Hall conductivity in alpha-MnTe.
