Phase transitions : Cargèse 1980 by Maurice Lévy( Book )

9 editions published between 1981 and 1982 in English and held by 271 WorldCat member libraries worldwide

The understanding of phase transitions has long been a fundamental problem of statistical mechanics. It has made spectac ular progress during the last few years, largely because of the ideas of K.G. Wilson, in applying to an apparently quite different domain the methods of the renormalization group, which had been developped in the framework of the quantum theory of fields. The ability of these theoretical methods to lead to very precise predictions has, ~n turn, stimulated in the last few years more refined experiments in different areas. We now have entered a period where the theoretical results yielded by the renormalization group approach are suffi ciently precise and can be compared with those of the traditional method of high temperature series expansion on lattices, and with the experimental data. Although very similar, the results coming from the renormalization group and high temperature analysis seemed to indicate systematic discrepancies between the continuous field theory and lattice models. It was therefore important to appreciate the reliability of the predictions coming from both theoretical schemes, and to compare them to the latest experimental results. We think that this Cargese Summer Institute has been very successful 1 in this respect. Indeed, leading experts in the field, both experimentalists and theoreticians, have gathered and presented detailed analysis of the present situation. In particular, B.G. Nickel has produced longer high temperature series which seem to indicate that the discrepancies between series and renormalization group results have been previously overestimated
Large-order behaviour of perturbation theory by Jean-Claude Le Guillou( Book )

11 editions published between 1990 and 2012 in English and held by 139 WorldCat member libraries worldwide

This volume is concerned with the determination of the behaviour of perturbation theory at large orders in quantum mechanics and quantum field theory, and its application to the problem of summation of perturbation series.Perturbation series in quantum field theory and in many quantum mechanics models are only asymptotic and thus diverge for all values of the expansion parameter. Their behaviour at large orders provides information about whether they define the theory uniquely (the problem of Borel summability). It suggests methods to extract numerical information from the series when
Théories des champs invariantes conformes bidimensionnelles by Philippe Di Francesco( Book )

1 edition published in 1989 in French and held by 6 WorldCat member libraries worldwide

CET OUVRAGE EST CONSACRE A L'ETUDE DES THEORIES DE CHAMPS BIDIMENSIONNELLES INVARIANTES PAR ROTATION, TRANSLATION ET DILATATION LOCALES, QUI DOIVENT DECRIRE LES CLASSES D'UNIVERSITALITE DES PHENOMENES CRITIQUES A DEUX DIMENSIONS. CES THEORIES SONT ENGENDREES EN GENERAL PAR DES QUOTIENTS DE THEORIES DE WESS-ZUMINO-WITTEN BASEES SUR DES GROUPES DE LIE COMPACTS. NOUS PROPOSONS UNE METHODE DE REPRESENTATION DE CELLES-CI EN TERMES DE GAZ DE CHARGES ELECTRIQUES ET MAGNETIQUES EN INTERACTION COULOMBIENNE, QUI PERMET DE LES RESOUDRE EXACTEMENT, Y COMPRIS EN GEOMETRIE FINIE, SUR LE TORE PAR EXEMPLE. CETTE REPRESENTATION EST LIEE AUX MODELES INTEGRABLES SOUS JACENTS ET INTRODUIT LE CONCEPT DE CHARGE FLOTTANTE GENERALISANT AU CAS DE LA GEOMETRIE FINIE LA NOTION DE CHARGE A L'INFINI, QUI MODIFIE LA STRUCTURE D'UNE THEORIE CONFORME EN DECALANT L'ENSEMBLE DE SES ETATS PHYSIQUES. ENFIN, APRES AVOIR DETAILLE LES PROPRIETES GENERALES DES THEORIES CONFORMES RATIONNELLES, NOUS PROPOSONS UNE APPROCHE ORIGINALE DU PROBLEME DE LEUR CLASSIFICATION, T REMPLACE PAR CELUI DE DETERMINATION DES DIAGRAMMES DONT LES MATRICES D'INCIDENCE VERIFIENT UN CERTAIN NOMBRE DE PROPRIETES SPECTRALES, EN RELATION AVEC LES SOUS-GROUPES D'UN GROUPE DE LIE COMPACT DONNE
