Session Abstract

Quasicrystals are a form of matter that is ordered but not periodic. They are found in bulk alloys, as thin films, and in various forms of soft matter. Recent research elucidated the crystallographic structure of quasicrystals, analyzed their formation process, tested thermodynamic stability, investigated mathematical aspects of quasiperiodic tilings, advanced their understanding through models and simulations, measured electronic and physical properties, and described their practical applications. These and related topics involving experimental or theoretical research in quasicrystals are the subject of this session.
