Abstract:

Thesis advisor: Ziqiang Wang<br>Gutzwiller wave function is an important theoretical technique for treating local electron-electron correlations nonperturbatively in condensed matter and materials physics. It is concerned with calculating variationally the ground state wave function by projecting out multi-occupation configurations that are energetically costly. The projection can be carried out analytically in the Gutzwiller approximation that offers an approximate way of calculating expectation values in the Gutzwiller projected wave function. This approach has proven to be very successful i

Abstract:

Thesis advisor: Ziqiang . Wang<br>The transition between many-body localized states and the delocalized thermal states is an eigenstate phase transition at finite energy density outside the scope of conventional quantum statistical mechanics. We apply support vector machine (SVM) to study the phase transition between many-body localized and thermal phases in a disordered quantum Ising chain in a transverse external field. The many-body eigenstate energy E is bounded by a bandwidth W=Eₘₐₓ-Eₘᵢₙ. The transition takes place on a phase diagram spanned by the energy density ϵ=2(Eₘₐₓ-Eₘᵢₙ)/W and the

Full text

Abstract:

We study the Weyl representation of metaplectic operators associated to a symplectic matrix having no non-trivial fixed point, and justify a formula suggested in earlier work of Mehlig and Wilkinson. We give precise calculations of the associated Maslov-type indices; these indices intervene in a crucial way in Gutzwiller’s formula of semiclassical mechanics, and are simply related to an index defined by Conley and Zehnder.

Abstract:

On étudie le comportement semi-classique d'hamiltoniens quantiques dont le symbole de Weyl est invariant par un groupe de symétries. La réduction quantique consiste à restreindre le hamiltonien aux sous-espaces de symétrie de L^2(R^n) donnés par la décomposition de Peter-Weyl. Les opérateurs restreints sont appelés hamiltoniens quantiques réduits. Pour un groupe fini, on donne une formule de Gutzwiller pour le hamiltonien réduit qui fait intervenir la symétrie d'orbites périodiques classiques du niveau d'énergie étudié. On l'interprète dans l'espace de phase réduit lorsque le groupe agit libre

Nous etudions le modele de hubbard, le modele a deux bandes du plan cuo#2 et le modele t-j, dans une large gamme des valeurs de leurs parametres. Pour ce faire, nous utilisons la methode de gutzwiller que nous avons generalisee. Pour le compose la#2cuo#4, nous retrouvons la bonne valeur du moment alterne, le comportement isolant au-dessus de la temperature de neel et le transfert de charge observe lors du dopage.

Abstract:

This thesis is devoted to a study of the effect of disorder on strongly correlated electrons. For non-interacting electrons, Anderson localization occurs if the amount of disorder is sufficient. For disorder-free systems, a Mott metal-insulator transition may occur if the electron-electron interactions are strong enough. The question we ask in this thesis is what happens when both disorder and interactions are present. We study the Anderson-Hubbard model, which is the simplest model to include both interactions and disorder, using a Gutzwiller variational wave function approach. We then study
