Full textWe study magnetic and one-particle properties of the 2d hubbard model within the framework of a non-linear sigma model (nlsm) description of spin fluctuations the theory rests upon the assumption of local antiferromagnetic (af) ordering. It is valid at all coulom interaction strengths, below a cross-over temperature marking the onset of af short-range order. At half-filling, we derive the magnetic phase diagram and compute the fermion spectral function. At zero temperature, long-range af order is shown to be present for all values of the coulomb repulsion. The ground-state exhibits a smooth transition from a slater-like behavior at weak coupling, to a mott-heisenberg-like behavior at strong coupling. At finite temperatures the af order is suppressed, in agreement with the mermin-wagner theorem, but the af correlation length remains exponentially large with respect to the lattice spacing, we develop a new technique for calculating the spectral function and the density of states, which takes into account the highly non-gaussian nature of magnetic fluctuations. We establish the existence of a transition between a weak-coupling regime exhibiting a pseudogap at finite temperatures, and a strong-coupling regime where one-particle excitations are gapped. The properties of bogoliubov quasi particles at zero temperature and of their precursors at finite temperatures are analyzed. Away from half filling, a new method for deriving the low-energy effective action is proposed. The effective model involves low-energy bogoliubov quasi particles coupled to a nlsm. The low-energy action is critically compared to known phenomenological nlsm-fermion theories

Full textIn this thesis we study some geometric constructions appearing naturally in the context of sigma models, their gauging and supersymmetrization. The thesis consists of three parts. The first part (chapters 1 and 2) contains facts coming from classical differential geometry and graded geometry, they are needed to understand the main results of the thesis. We review the geometric constructions related to Poisson and symplectic manifolds. We generalize these notions to Dirac and n-plectic manifolds and establish the links with Courant algebroids. The main language used in the thesis for mathematical description of the sigma models is the graded geometry - we thus define the basis of calculus on supermanifolds and graded manifolds, as well as describe the notions of Q-structures and multigraded manifolds. The main goal of the second part (chapters 3 and 4) is to interpret geometrically the gauge invariance of some sigma models. We establish the relation of the symmetries of the Dirac sigma model, and as a particular case of the (twisted) Poisson sigma model, with the subalgebra of sections of Courant algebroid. We generalize the notion of equivariant cohomology, that permits to recover the sigma models with a prescribed group of gauge symmetries. In particular we construct the necessary groups for the mentioned sigma models. The third part (chapter 5) addresses the graded extension of the sigma models (like in supersymmetrization). It is in fact related to the geometric structures that can be defined on the space of maps between multigraded manifolds

Full textUn faisceau de photons étiquetés et polarisés linéairement a été produit en rétrodiffusant un faisceau laser sur le faisceau d'électrons de 6 GeV de l'anneau de l'ESRF. La cible a été d'hydrogène liquide de 3 cm. Un détecteur 4 pi a été utilisé, composé de trois couches de détecteurs: chambres à fil, compteurs à scintillation et calorimètres. Nous avions la charge d'installer et d'étalonner un double mur de scintillants (3x3 m) conçu pour détecter aux angles avant (1-25°) les particules chargées et mesurer leur pertes d'énergie et leurs temps de vol.
Nous avons analysé les résultats de la réaction g p -> eta p en identifant le eta dans le calorimètre latéral qui est une boule BGO et en détectant le proton dans les détecteurs à scintillation.
L'asymètrie faisceau Sigma a été extraite des distribution en phi du méson éta et a été établie en fonction de theta CM du eta pour 6 intervalles d'énergie incidentes allant du seuil jusqu'à 1100 MeV.
L'interprétation des résultats de l'asymètrie Sigma a été effectuée dans le cadre du modèle isobarique. La prise en compte des deux résonances, S11(1535) et D13(1520) n'a pas suffi pour expliquer nos résultats.
Il a fallu inclure en plus l'excitation des résonances P13(1720) et D13(1675) et P13(1880) la dernière étant manquante dans le tableau des résonances et récemment revélée par le modèle des quarks.

Full textNous proposons d'une part une nouvelle formulation variationnelle du problème hydrostatique aboutissant à un problème semi-discretisé en temps bien posé. Nous en faisons l'analyse mathématique et nous montrons quelques résultats numériques obtenus après programmation de l'approximation de ce problème dans le logiciel Telemac-3D développé au Laboratoire National d'Hydraulique et Environnement (LNHE) d'edf.
D'autre part, nous étudions la réinterprétation dans le cadre ALE de la méthode de discrétisation verticale de domaines tridimensionnels appelée transformation sigma, et nous en proposons une généralisation permettant d'améliorer la représentation des stratifications dans un écoulement
Finalement, nous présentons un schéma ALE-MURD conservatif pour la résolution des équations de convection linéaires posées sur un domaine mobile. Une condition particulière doit être vérifiée afin que le schéma soit conservatif lorsque le domain bouge effectivement. Nous montrons comment assurer cette contrainte dans le cas particulier où le domaine est tridimensionnel et ne bouge que selon la verticale. Ce résultat est illustré dans le cadre des écoulements à surface libre en dimension trois.
