Book Description
The conception of lasers and optoelectronic devices such as solar cells have been made possible, thanks to the modern day mastery of processes that harness the interaction of electromagnetic radiation with matter. This first volume is dedicated to thermal radiation and experimental facts that reveal the quantification of matter. The study of black body radiation allows the introduction of fundamental precepts such as Plancks law and the energy-related qualities that characterize radiation. The properties of light and wave–particle duality are also examined, based on the interpretation of light interferences, the photoelectric effect and the Compton effect. This book goes on to investigate the hydrogen atomic emission spectrum and how it dovetails into our understanding of quantum numbers to describe the energy, angular momentum, magnetic moment and spin of an electron. A look at the spectroscopic notation of the states explains the different wavelengths measured from the splitting of spectral lines. Finally, this first volume is completed by the study of de Broglies wave theory and Heisenbergs uncertainty principle, which facilitated the advancement of quantum mechanics.

Book Description
La physique quantique permet de comprendre en profondeur les phénomènes qui régissent le comportement des solides, des semi-conducteurs, des atomes, des particules élémentaires et de la lumière. Cette nouvelle édition contient trois chapitres entièrement re-rédigés, un nouveau chapitre sur la mécanique quantique relativiste (construction de Wigner et équation de Dirac), une sélection de corrigés d’exercices et de nombreuses mises à jour. Elle offre une approche originale permettant de traiter immédiatement et de façon simple des applications importantes comme l’atome à deux niveaux, le laser ou la résonance magnétique nucléaire. Le formalisme est ensuite développé en privilégiant l’utilisation des symétries et permet de traiter les applications usuelles comme le moment angulaire, les approximations semi-classiques, la théorie de la diffusion ou la physique des atomes et des molécules. L'ouvrage accorde aussi une large place à des domaines nouveaux apparus depuis une trentaine d’années et qui occupent aujourd’hui le devant de la scène : non-localité et information quantiques, refroidissement d’atomes par laser, condensats de Bose-Einstein, états du champ électromagnétique, sujets qui ne sont pas traités dans la plupart des manuels. Ce livre s’adresse aux étudiants de L3 et de master de physique et aux élèves des écoles d’ingénieurs. Il est également susceptible d’intéresser un large public de physiciens, chercheurs ou enseignants, qui souhaitent s’initier aux développements récents de la physique quantique.

Book Description
Au début du XXe siècle, la science semblait complète et les lois de la nature presque toutes découvertes, mais des chercheurs intrépides ont réveillé un géant endormi en découvrant la mécanique quantique. Dans le monde quantique, les objets peuvent se trouver en deux endroits à la fois, le voyage dans le temps est non seulement possible, mais nécessaire, la cause et l'effet peuvent s’inverser, et la simple observation d'un objet change son état. Des univers parallèles à l'antimatière, laissez-vous guider par le facétieux Tim James à la découverte des bizarreries du monde de l'infiniment petit !

Book Description
The second volume of the proceedings of the international seminar devoted to locali· zation and delocalization in quantum chemistry is divided into four parts. The first one is mainly concerned with the localizability of electrons in ionized and exited states. The second part shows how is it possible to take advantage of the localizability of electrons to compute molecular wave-functions. The third part of the book is an homogeneous analysis of the electronic collective excitation and of the motion of excitons in organic solids. The last section is devoted to the study of the role of electron localizability in the chemical reactivity of molecules. Concluding remarks are concerned with a careful analysis of the localizability concept itself in relation with a possible interpretation of the wave-mechanics. PART I ELECTRON LOCALIZATION IN IONIZED AND EXCITED STATES APPLICATIONS OF PAIR DENSITY ANALYSIS R. CONSTANCIEL and L. ESNAULT Centre de Mecanique Ondulatoire Appliquee, Paris, France Abstract. The method of pair density analysis is applied to various kinds of calculations. We examine the influence of the quality of the wavefunction and of the nuclear configuration; the problem of hybridization is discussed, as weIl as the relations between separability and excitation.

Book Description
Quantum mechanics is the foundation of modern technology, due to its innumerable applications in physics, chemistry and even biology. This second volume studies Schrödingers equation and its applications in the study of wells, steps and potential barriers. It examines the properties of orthonormal bases in the space of square-summable wave functions and Dirac notations in the space of states. This book has a special focus on the notions of the linear operators, the Hermitian operators, observables, Hermitian conjugation, commutators and the representation of kets, bras and operators in the space of states. The eigenvalue equation, the characteristic equation and the evolution equation of the mean value of an observable are introduced. The book goes on to investigate the study of conservative systems through the time evolution operator and Ehrenfests theorem. Finally, this second volume is completed by the introduction of the notions of quantum wire, quantum wells of semiconductor materials and quantum dots in the appendices.
