The Com­mis­sion on Ape­ri­od­ic Crys­tals  of the In­ter­na­tion­al Union of Crys­tal­log­ra­phy (IU­Cr)  organises the 4th edition of the school “International school on aperiodic Crystals” (ISAC4).

This school will take place in Portbail (Normandy) from September 8 to 14 2019. The tar­get­ed  au­di­ence is clear­ly a non-spe­cial­ist one: Phd stu­dents, young 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 Normandy, north-west of France. Ex­perts in the field of ape­ri­od­ic crys­tal will give lec­tures, in a tu­to­ri­al way and on a step by step ba­sis. The num­ber of par­tic­i­pants will be lim­it­ed to 40 in or­der to fa­cil­i­tate ex­changes. Af­ter an in­tro­duc­tion to the high di­men­sion­al con­cept, the ba­sis  of the struc­ture de­ter­mi­na­tion of ape­ri­od­ic crys­tal will be in­tro­duced for each class of ape­ri­od­ic crys­tals. Var­i­ous ex­am­ples will then be pre­sent­ed, to­geth­er with overviews on phase tran­si­tions, phonons and pha­sons, sim­u­la­tions and ape­ri­od­ic crys­tal sta­bil­i­ty.Tu­to­ri­al in small groups (20) will al­so be or­ga­nized in or­der to prac­tice the no­tions learned in the lec­tures.
