Presentation
Aperiodic crystals are long range ordered structures which lack translational invariance. They are found in a large variety of systems (minerals, organic compounds, single element under pressure, oxides, ferro-electrics, intermetallic compounds) and encompass incommensurately modulated structures, incommensurate composites and quasicrystals.
The structure determination of aperiodic crystals and the influence of the aperiodic order on their physical properties have made tremendous progress in recent years. However the high dimensional description and superspace approach used to describe the atomic structure of aperiodic crystal remain difficult to grasp for the non specialist.
This is why the Commission on Aperiodic Crystals of the International Union of Crystallography (IUCr) has decided to organize a school on Aperiodic Crystals.
The targeted audience is clearly a non-specialist one: Phd students or experienced scientists working in the field of crystallography, chemistry, material science or solid state physic and willing to have a basic understanding of aperiodic crystals.
The school will be organized on 5 days in Kutna Hora, a historical town located 80 km east of Prague. Experts in the field of aperiodic crystal will give lectures and organize tutorials on a step by step basis for each class of aperiodic crystals. Various examples will then be presented, together with overviews on phase transitions, phonon and phasons, simulations and aperiodic crystal stability.
Number of participants will be limited to 40.
School location
The school will take place in Kutna Hora, a historical town 80 km from Prague. The weather is expected to be nice and mild at this season. Housing will be on-site in a hotel U Kata.
St Barbara's cathedral, Kutna Hora

Registration and deadlines
Pre-registration: by e-mail to dusek@fzu.cz. Deadline 15 April 2022.
Registration: follow instructions obtained after pre-registration. Deadline 15 May 2022.
Warning: only 40 places available!!
Registration fees. Registration fees are all inclusive, i.e. they include the school fee, the cost of the hotel and full board, the stay expenses, the gala dinner and excursion. The arrival is on Sunday 22 May 2022 from 16h and departure on Friday 27 May 2022 afternoon. Housing will be in a 3 star type hotel on the basis of double occupancy at request and single occupancy for other cases.
Young Scientists fee: 150 €. Young scientists are graduate students, post-graduate students or post-doctoral fellows with a maximum age of 35.
Senior scientists fee: 400 €.
Retired scientists: free.
Pre-registration, registration and payment.The registration is in two steps. First pre-register by e-mail to Michal Dusek, dusek@fzu.cz. Please mention if you are a young scientist (see the definition above) or retired. After a few days, you will receive a confirmation and a link to proceed for final registration. Payment can be made by Credit Card (preferred), bank transfer or invoice.
Support from sponsors. Limited budget is available from our sponsors for travelling support and registration fee waivers. Young scientists applying for this support should send their CV, motivation letter and supporting letter from their supervisor as a part of their pre-registration. Other scientists should explain why they need the travelling support or registration fee waiver.
Pandemic planning. The School is planned as a classical in-person event. In case of bad epidemic situation, we will change to on-line event and registration fees will be returned.
