Interplay between Point-Group Symmetries and the Choice of the Bloch Basis in Multiband Models
We analyze the point-group symmetries of generic multiband tight-binding models with respect to the transformation properties of the effective interactions. While the vertex functions in the orbital language may transform non-trivially under point-group operations, their point-group behavior in the...
