Site symmetry of the Double Layer Space Groups

Site Symmetry Method
This program implements the so-called site-symmetry approach for double layer space groups. The method establishes symmetry relations between the localized states (local atomic displacements) and crystal extended states (phonons, electrons, etc.) over the entire Brillouin zone.
Input data:
1. Layer space group number.
2. k-vector.
3. Wyckoff position.
Reference. For more information about this program see the following article:

  • If you are using this program in the preparation of an article, please cite the above reference.
    Please, enter the sequential number of the layer group as given in the International Tables for Crystallography, Vol. A
