School on Fundamental Crystallography

Mahdia, Tunisia, 9-13 April 2012

Organized by the Commission on Mathematical and Theoretical Crystallography (MaThCryst) and the Tunisian Crystallographic Association (Association Tunisienne de Cristallographie), in cooperation with the IUCr Commission on Crystallographic Teaching (CT).


Program

FUNDAMENTALS BASIC CONCEPTS
CRYSTALLOGRAPHY IN DIRECT SPACE
PHYSICS OF DIFFRACTION AND CRYSTALLOGRAPHIC IN RECIPROCAL SPACE
CRYSTALLOGRAPHY ONLINE: SHORT PRACTICAL COURSE ON THE USE AND APPLICATIONS OF THE BILBAO CRYSTALLOGRAPHIC SERVER

The aim of the course is to give a tutorial and practical guide to the crystallographic databases and some of the computer tools available on the Bilbao Crystallographic Server (www.cryst.ehu.es). Online exercises will help the participants to get some practical experience in the use and applications of the computer programs in treating problems of theoretical crystallography, solid-state physics and crystal chemistry.

  1. Databases and computer tools for group-subgroup relations between space groups
    1. Crystallographic databases and access tools
      1. Space-group symmetry databases (International Tables for Crystallography, Volume A: Space-group symmetry)
      2. Maximal subgroups and minimal supergroups (International Tables for Crystallography, Volume A1: Symmetry relations between space groups)
      3. Brillouin-zone database
    2. Group-subgroup relations between space groups
      1. Study of general group-subgroup pair of space groups; Hermann theorem: twins and antiphase domains; coset decompositions. Supergroups of space groups
      2. Symmetry relations between Wyckoff positions for group-subgroup pairs; Baernighausen trees constructions
    3. Structure utilities and tools
      1. Equivalent structure descriptions; structure descriptions with respect to different space-group settings
      2. Comparison between different descriptions of the same structure
      3. Computer tools for the study of structural relationships
  2. Tools for structural phase transitions on the Bilbao Crystallographic Server
    1. Structural pseudosymmetry
      1. Methods of pseudosymmetry search using supergroups of space groups
      2. Search for new ferroelectric and ferroelastic materials
    2. Phase transitions with group-subgroup relations between the space groups of the two phases
      1. Inverse Landau problem
      2. Symmetry-mode analysis of displacive phase transitions
