Layer Site Symmetry

Site Symmetry Method
This program implements the so-called site-symmetry approach. 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 group number as given in ITE.
  2. k-vector data :
    • Reciprocal lattice basis type, which may be primitive (as in Cracknell-Davies-Miller-Love tables), or dual to the conventional (ITA)
    • k-vector coordinates relative to chosen basis as any three decimal numbers or fractions.
    • Label of the k-vector (up to three letters).
Please, enter the sequential number as given in International Tables for Crystallography, Vol. E or
