This is a Crystallographic Book List - but what is Crystallography? We take the following working definition. Crystallography is the branch of science concerned with the description and understanding of the structure and properties of condensed states of matter in terms of the spatial relationships of atoms and interatomic forces in an extended array_ Moreover A Crystallographer is a scientist with an active interest in Crystallography, either for its own sake or for the contribution it can make to some other branch of science. (Obviously this defi nition is not an exclusive one) The problem of deciding what books should be included in this List made it necessary to think what topics are comprised in Crystallography, and to clarify the issue a draft syllabus was constructed, and is set out below. Though it probably covers too wide a spectrum for anyone indivi dual (or University Department) to deal with in detail, there is no part of it which would not be regarded by some Crystallographers as quite essential. It is apparent that some topics are central to Crystallo graphy - notably crystal geometry and symmetry, diffraction by perfectly and imperfectly periodic structures, methods of structure analysis, and the relation of physical and chemical properties to structure - and others are peripheral, linking the central topics to other fields of knowledge."
L'ouvrage Mecanique Quantique - Introduction - jette les bases du cours de mecanique quantique et de la theorie des champs. En partant de la radiation du corps noir, de l'effet photoelectrique et de la dualite onde - particule, l'auteur expose les relations de l'incertitude, le spin, et les systemes a plusieurs corps. Il inclut les applications a l'atome d'hydrogene et les experiences de Stern-Gerlach, et de Einstein-de Haas. Sont aussi presentes en details l'aspect mathematique de la theorie de representation, les matrices S, la theorie de la pertubation, les problemes des valeurs propres, les equations differentielles hypergeometriques. Le lecteur trouvera aussi plus de 80 exemples et exercices, ainsi que leur corrige, et ceci afin de consolider le propos du livre. Chaque exercice a ete soigneusement choisi et traite pour que l'ouvrage soit l'outil de base et de reference de son lecteur."
L'ouvrage traite d'un concept particulierement attractif du cours de mecanique quantique avance, c'est a dire les symetries. Apres une breve introduction aux symetries en mecanique classique, le texte s'attache a leur place en mecanique quantique, aux consequences de la symetrie de rotation, ainsi qu'a la theorie generale des groupes de Lie. Les groupes isospin, l'hypercharge SU(3), et leurs applications sont traites avant les chapitres sur les quarks et leur charme, SU(4), ainsi que les symetries dynamiques et les frontieres de la recherche en physique des particules. Ce texte unique comprend plus de 120 problemes et exercices tres detailles et corriges, afin d'en faire l'ouvrage de reference en la matiere.
