Book Description
Ce travail de thèse a pour objectif l'amélioration et le développement de méthodes de prise en compte des vibrations atomiques dans les calculs ab initio de spectres d'absorption des rayons X, basés sur la théorie de la fonctionnelle de la densité (DFT) en ondes planes avec pseudo-potentiels.Des spectres expérimentaux au seuil K de l'aluminium dans le corindon et le béryl ont été mesurés pour des températures allant de 300 à 930K, dans le but d'observer l'impact des vibrations thermiques sur les structures spectrales.Des modèles théoriques ont été développés pour essayer, par le calcul numérique, de rendre compte des effets expérimentaux, notamment au niveau du pré-seuil.Le problème connexe du core level shift a également été étudié sur la sillimanite, l'andalousite et le germanate de potassium, en rapport avec la simulation numérique par DFT.Ce phénomène intervient lorsque, dans un matériau cristallin, deux ou plus atomes d'un même type sont présents dans des sites non-équivalents.

Book Description
Mesure des sections efficaces d'ionisation d'éléments 15 ≤ z ≤82 par impact de protons (4-22 MEV) ou de particules alpha (10-30 MEV). Comparaison aux calculs à l'approximation de Born ou de la rencontre binaire : bon accord pour l'ionisation en couche k, moins bon pour les couches l et m. Possibilités de cette méthode en analyse suivant divers paramètres : nature et énergie des particules incidentes, bruit de fond, nature de la cible, etc. exemples de résultats obtenus par cette méthode, rapide et sensible, lors du dosage, d'éléments polluants recueillis sur des filtres de prélèvements atmosphériques

Book Description
Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book Description
This new, third volume of Cohen-Tannoudji's groundbreaking textbook covers advanced topics of quantum mechanics such as uncorrelated and correlated identical particles, the quantum theory of the electromagnetic field, absorption, emission and scattering of photons by atoms, and quantum entanglement. Written in a didactically unrivalled manner, the textbook explains the fundamental concepts in seven chapters which are elaborated in accompanying complements that provide more detailed discussions, examples and applications. * Completing the success story: the third and final volume of the quantum mechanics textbook written by 1997 Nobel laureate Claude Cohen-Tannoudji and his colleagues Bernard Diu and Franck Laloë * As easily comprehensible as possible: all steps of the physical background and its mathematical representation are spelled out explicitly * Comprehensive: in addition to the fundamentals themselves, the books comes with a wealth of elaborately explained examples and applications Claude Cohen-Tannoudji was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris where he also studied and received his PhD in 1962. In 1973 he became Professor of atomic and molecular physics at the Collège des France. His main research interests were optical pumping, quantum optics and atom-photon interactions. In 1997, Claude Cohen-Tannoudji, together with Steven Chu and William D. Phillips, was awarded the Nobel Prize in Physics for his research on laser cooling and trapping of neutral atoms. Bernard Diu was Professor at the Denis Diderot University (Paris VII). He was engaged in research at the Laboratory of Theoretical Physics and High Energy where his focus was on strong interactions physics and statistical mechanics. Franck Laloë was a researcher at the Kastler-Brossel laboratory of the Ecole Normale Supérieure in Paris. His first assignment was with the University of Paris VI before he was appointed to the CNRS, the French National Research Center. His research was focused on optical pumping, statistical mechanics of quantum gases, musical acoustics and the foundations of quantum mechanics.
