Book excerpt: DANS LE CADRE DE LA MECANIQUE CLASSIQUE, ON PROPOSE UN FORMALISME CONDUISANT A LA DISTRIBUTION STATISTIQUE DE L'ENERGIE SUR LES PRODUITS D'UNE REACTION D'ECHANGE A TROIS ATOMES. DANS UN PREMIER TEMPS, ON TRAITE DE FACON RIGOUREUSE LE CAS DES REACTIONS GOUVERNEES PAR DES FORCES A LONGUE PORTEE (A PARAITRE A CHEM. PHYS.). DANS UNE DEUXIEME PARTIE, UN TRAITEMENT PARTIEL DE LA CONSERVATION DU MOMENT ANGULAIRE TOTAL PERMET DE METTRE EN EVIDENCE LES PRINCIPAUX FACTEURS INFLUENCANT LA FORME DE LA DISTRIBUTION DE L'ENERGIE DE RECUL DES PRODUITS FORMES.

Available in PDF, EPUB and Kindle. Book excerpt: Ce travail presente deux etudes theoriques dans le domaine de la dynamique moleculaire a deux atomes. La premiere etude concerne les effets d'alignement lors du transfert avec changement de spin (4s5p #1p4s5p #3p) dans l'atome ca par collision avec un atome he. Ces effets ont ete mis en evidence recemment dans des experiences de jets croises mettant en jeu deux lasers polarises rectilignement, l'un pour aligner initialement l'atome dans l'etat #1p l'autre pour sonder l'alignement final dans l'etat #3p. Tous les effets d'alignement peuvent etre caracterises par un jeu de sections efficaces exprimees dans un referentiel fixe de l'espace, le referentiel de collision. Par une approche quantique independante du temps, nous avons determine les sections efficaces de transfert dans le referentiel de collison pour trois jeux de potentiels des etats electroniques du systeme ca-he. Les resultats sont compares aux resultats experimentaux. La deuxieme etude est consacree a la dynamique de la dissociation de hc1 apres la photoexcitation de la molecule dans l'etat electronique repulsif a#1ii. La photodissociation de la molecule laisse les fragments dans leur etat electronique le plus bas en energie h(#2s) et c1(#2p). Notre etude est basee sur la theorie independante du temps de la photodissociation de molecules diatomiques. Nous avons determine la section efficace totale de photodissociation et les sections efficaces partielles de production de l'atome c1 dans l'une ou l'autre des deux composantes de structure fine (#2p#1#/#2 et #2p#3#/#2). Pour interpreter nos resultats et pour comprendre les mecanismes susceptibles d'affecter les populations dans les deux composantes #2p#1#/#2 et #2p#3#/#2 nous presentons, d'une part un calcul de redistribution du flux quantique dans les etats adiabatiques en fonction de la distance entre les deux atomes et d'autre part la determination, dans une approche semi-classique de l'evolution temporelle des probabilites de transition dans la base des etats adiabatiques.

Available in PDF, EPUB and Kindle. Book excerpt: In recent years statistical physics has made significant progress as a result of advances in numerical techniques. While good textbooks exist on the general aspects of statistical physics, the numerical methods and the new developments based on large-scale computing are not usually adequately presented. In this book 16 experts describe the application of methods of statistical physics to various areas in physics such as disordered materials, quasicrystals, semiconductors, and also to other areas beyond physics, such as financial markets, game theory, evolution, and traffic planning, in which statistical physics has recently become significant. In this way the universality of the underlying concepts and methods such as fractals, random matrix theory, time series, neural networks, evolutionary algorithms, becomes clear. The topics are covered by introductory, tutorial presentations.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book The Mis Behaviour of Markets written by Benoit B. Mandelbrot and published by Profile Books. This book was released on 2010-10-01 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: This international bestseller, which foreshadowed a market crash, explains why it could happen again if we don't act now. Fractal geometry is the mathematics of roughness: how to reduce the outline of a jagged leaf or static in a computer connection to a few simple mathematical properties. With his fractal tools, Mandelbrot has got to the bottom of how financial markets really work. He finds they have a shifting sense of time and wild behaviour that makes them volatile, dangerous - and beautiful. In his models, the complex gyrations of the FTSE 100 and exchange rates can be reduced to straightforward formulae that yield a much more accurate description of the risks involved.
