    • Therefore, BFO does not fall into the category of materials that are addressed in Ref. and that exhibit multiple, rather than none primary OPs, each belonging to a single irreducible representation.

    • Similarly, FE and AFD motions do not want to coexist in an orthorhombic phase in which u would be parallel to the 001 direction and ωR would lie along another 001 direction (being perpendicular to u) because of the positive, large Dxxyy.

    • Alternatively, one can also consider that this unusual phase transition has a multicomponent primary OP, that is (u1, u2, u3, ω1 R, and ω2 R), involving two different irreducible representations [rather than a single one as assumed in the conventional Landau theory (Ref.)].
