Session Abstract

Quantum crystallography has undergone rapid development in the last few years. Application of new theoretical approaches in crystallographic studies has led to improvements in the quality of the final refinement results. There are plenty of strong discussions at scientific conferences in our field regarding the meaning and understanding of the term quantum crystallography. We would like to have this MS for the newest advances and challenges in quantum crystallography, to cover some unique topics and research which cannot be fitted into any of the more specialized MS. We hope that it will be a platform for discussion of the fundamentals of the field.
