Abstract:
We study the momentum distribution of the electrons in an extended periodic Anderson model, where the interaction,Ucf, between itinerant and localized electrons is taken into account. In the symmetric half-filled model, due to the increase of the interorbital interaction, thefelectrons become more and more delocalized, while the itinerancy of conduction electrons decreases. Above a certain value ofUcfthefelectrons become again localized together with the conduction electrons. In the less than half-filled case, we observe thatUcfcauses strong correlations between thefelectrons in the mixed valence regime.

Abstract:
In this thesis, an extended periodic Anderson model with an additional local Coulomb repulsion U f c between localized f electrons and conduction electrons is investigated by use of the projector-based renormalization method (PRM). First, it is shown that the model in one dimension shows a valence transition, which becomes sharper, when the energy of the f level approaches the Fermi level. The transition becomes also enhanced, when the hybridization V between the localized and conduction electrons decreases, for the case that the total number of electrons is fixed. In the two-dimensional case, one finds a similar valence transition behavior. However, in the valence transition regime also a superconducting phase may occur. To investigate this phase, we start from an Hamiltonian which includes small gauge symmetry breaking fields. We derive renormalization equations, from which the superconducting pairing functions are self-consistently determined. Our analytical and numerical results show that d- wave superconductivity becomes dominant in the valence transition regime. This confirms the suggestion by Miyake that valence fluctuations may lead to superconductivity in the Ce based heavy-fermion systems under high pressure
In dieser Arbeit wird mit Hilfe der projektiven Renormierungsmethode (PRM) ein erweitertes periodische Anderson Modell untersucht, das zusätzlich eine Coulomb-Abstoßung zwischen den lokalisierten f-Elektronen und den Leitungselektronen enthält. In einer Dimension zeigt das Modell einen Valenzübergang, wenn sich die Energie des f-Niveaus der Fermienergie nähert. Der Übergang wird ebenfalls schärfer, wenn bei festgehaltener Gesamtelektronenzahl die Hybridisierung V zwischen den lokalisierten und den Leitungselekronen abnimmt. In zwei Dimensionen findet man ein ähnliches Valenzübergangsverhalten. Allerdings kann zusätzlich eine supraleitende Phase im Valenzübergangsgebiet auftreten. Um die supraleitende Phase zu untersuchen, betrachten wir einen Hamiltonoperator mit kleinen zusätzlichen Feldern, die die Eichsymmetrie brechen. Wir leiten Renormierungsgleichungen her, aus denen sich die supraleitenden Paarfunktionen selbstkonsistent bestimmen lassen. Unsere analytischen und numerischen Resultate zeigen, dass im Valenzübergangsgebiet d-Wellen-Supraleitung dominiert. Dies bestätigt eine Vermutung von Miyake, dass Valenzfluktuationen in Ce-basierten Schwerfermionensystemen bei hohen Drücken zur Supraleitung führen können

Abstract:
The coordinate Bethe ansatz can be extended to a model, the Lieb–Liniger model, of a one-dimensional gas of Bosons interacting with repulsive δ‎-function potentials. It has attracted attention due to its relevance for experimental developments in the fields of ultracold gases and optical lattices. This chapter provides an exposition of the related classical nonlinear Schrödinger equation, followed by its generalization to the quantum model. It explores a limiting case, the Tonks-Girardeau gas. The δ‎-function potentials supply a kind of boundary condition on the wave functions allowing us to analyze the eigenfunctions of the Bethe ansatz, which are examined on the infinite line and for periodic boundary conditions. The latter leads to the Bethe ansatz equations. The solution of these equations is achieved in the thermodynamic limit for the ground state and for low-lying excited states.

Abstract:
Chapter 9 presents an introductory overview of quantum chemistry and solid state physics. First, the Periodic Table is examined in terms of atomic structure, electron orbitals and the shell model. Simple polar and non-polar molecules are considered in terms of the overlap of atomic orbitals which gives rise to covalent bonding between atoms. Hückel theory is used to analyse the electronic structure of benzene and polyene molecules. These ideas are extended to periodic solids. Bloch’s theorem is used to explain their band structure in terms of molecular orbital theory. Band theory provides an explanation of the distinctions between metals, semi-conductors and insulators. Caesium chloride is used to illustrate how the band structure and properties of an ionic compound arise from its atomic structure. Metals are discussed, with emphasis on copper as an illustrative example, and the significance of the Fermi surface is explained. Ferromagnetism is considered in the transition metals.

Abstract:
We study the occurrence in structures of a phenomenon similar to Anderson localization. This the vibration modes localization in structures composed of several nominally identical lightly coupled modular substructures. In an ideal perfect model, the vibration modes are global in nature, spreading to the whole structure. In real structures there are no two completely identical segments. Constructive or loading imperfections generate slight variation of the dynamic characteristics of each module. As the level of disorder grows and coupling between modules becomes lighter, the resulting vibration modes change considerably. Vibration energy may become confined to a few segments. This is the Mode Localization Phenomenon. We present models of long modular planar trussed structures. Light coupling is considered between the initially identical modules. A certain degree of imperfection is introduced by adopting a slight variation in the loading of the modules. This will generate a small variation in the global stiffness of the system as the axial loads in the bars affect their Geometric Stiffness Matrices.

Full text
Abstract:
The Fermi acceleration oscillator is extensively used to interpret many physical and mechanical phenomena. To understand dynamic behaviors of a particle (or a bouncing ball) in such a Fermi oscillator, a generalized Fermi acceleration model is developed. This model consists of a particle moving vertically between a fixed wall and the piston in a vibrating oscillator. The motion switching bifurcation of a particle in such a generalized Fermi oscillator is investigated through the theory of discontinuous dynamical systems. The analytical conditions for the motion switching are developed for numerical predictions. Thus, periodic motions in the Fermi-acceleration oscillator are given and the corresponding local stability and bifurcation are presented. Periodic and chaotic motions in such an oscillator are presented via the displacement time-history. From switching bifurcation and period-doubling bifurcation, parameter maps of periodic and chaotic motions will be developed for a global view of motions in the Fermi acceleration oscillator. To illustrate motion switching phenomena, the acceleration responses of the particle and base in the Fermi oscillator are presented. Poincare mapping sections are also used to illustrate chaos, and energy dissipation in chaotic motions can be evaluated.

Full text
Abstract:
The paper describes a homogenization technique for periodic lattice structures. The analysis is performed by considering the irreducible unit cell as a building block that defines the periodic pattern. In particular, the continuum equivalent representation for the discrete structure is sought with the objective of retaining information regarding the local properties of the lattice, while condensing its global behavior into a set of differential equations. These equations can then be solved either analytically or numerically, thus providing a model which involves a significantly lower number of variables than those required for the detailed model of the assembly. The methodology is first tested by comparing the dispersion relations obtained through homogenization with those corresponding to the detailed model of the unit cells and then extended to the comparison of exact and approximate harmonic responses. This comparison is carried out for both one-dimensional and two-dimensional assemblies. The application to three-dimensional structures is not attempted in this work and will be approached in the future without the need for substantial conceptual changes in the theoretical procedure. Hence the presented technique is expected to be applicable to a wide range of periodic structures, with applications ranging from the design of structural elements of mechanical and aerospace interest to the optimization of smart materials with attractive mechanical, thermal or electrical properties.

Abstract:
Abstract Superlattices with suppressed thermal conductivity are of great significance in the field of thermoelectricity and can improve the thermoelectric conversion efficiency of materials. Due to Anderson localization of coherent phonons, aperiodic superlattices have lower thermal conductivity than their periodic counterparts. At present, the thermal conductivity of superlattices is mostly predicted through ab initio or molecular dynamics simulations, which is computationally expensive and limits the size of the system. Meanwhile, there are many layered structural combinations for aperiodic superlattices, making it difficult to efficiently screen through all the combinations to search structures with the minimum thermal conductivity. In this work, based on a modified series thermal resistance model (STRM), a new effective medium theory (EMT) is established to predict the thermal conductivity of periodic and aperiodic superlattices. An adjacency factor near the maximum-resistance layers and a correction function, respectively, are introduced to account for the phonon coherence effect and the degree of randomization in the layer thickness. Combined with the genetic algorithm, EMT enables high-throughput screening of millions of aperiodic superlattice structures. This work demonstrates that the thermal conductivities of aperiodic superlattices at a wide range of system size can be constantly reduced to 1.4∼1.8 W/(m·K), which occurs at averaged periodic thicknesses in a stable range of 2.0∼2.5 nm.
