The software package SYMMODES (Symmetry Modes) provides
the necessary tools for a group-theoretical analysis of a structural phase
transition. For a given group - subgroup pair G > H the program constructs
the lattice of maximal subgroups relating G and H and calculates the
corresponding primary and secondary modes.
SYMMODES has been
developed in colaboration with H.Stokes and D.Hatch (Brigham Young University,
Utah, USA).
Input Data: In order to obtain the group - subgroup lattice G > H, input or
select the numbers of the group G, the subgroup H
and the index of H in G.
A tutorial on the application of several tools of this server including
SYMMODES in the study of group-subgroup phase transitions can be found
here.
