Abstract:
The three-dimensional electron-gas model has been a major focus for many-body theory applied to the electronic properties of metals and semiconductors. Because the model neglects band effects, whereas electronic systems are generally more strongly correlated in narrow band systems, it is most widely used to describe the qualitative physics of weakly correlated metals with unambiguous Fermi liquid properties. The model is more interesting in two space dimensions because it provides a quantitative description of electrons in quantum wells and because these can form strongly correlated many-parti

The focus of this work was to study the nanowire (NW) optical and structural properties on a single NW level. The GaAs-based heterostructured semiconductor NWs, grown by Au-assisted molecular beam epitaxy (MBE), were studied throughout this work. Due to diversity of the NWs within each growth batch, it is essential to study the same single NWs both by di erent micro-photoluminescence (PL) and transmission electron microscopy (TEM) techniques. An efficient method for such a correlated study was developed (paper I), and applied in all following studies. The key feature is that the single NWs of

Néanmoins, un quasi-ordre à longue distance peut exister, avec des fonctions de corrélation spin-spin décroissant en loi de puissance avec la distance, comme par exemple dans la chaîne de spin-1/2.

Abstract:
Two aspects of strongly correlated electron systems are studied in this thesis. Hubbard-type models are thought to be at the basis of high-critical-temperature superconductivity. One interaction which has not had much study is the nearest-neighbour hopping of on-site singlet pairs. We refine earlier renormalization group arguments and, using the density-matrix renormalization group method, numerically confirm their prediction that a spin gap opens at infinitesimal pair-hopping amplitude V > 0 in the one-dimensional tight-binding model. We also find a phase separation transition at a fin

Abstract:
Recent works have suggested that the defect induced magnetism in Diluted Magnetic Semiconductors (DMSs), Transition Metal Oxides (TMOs) and related materials is facilitated and enhanced by codoping and the synergistic action between the codopants. In the present work we demonstrate that the proposed defect synergy is the result of the interplay among correlated spin-polarization processes which take place in a successive way in neighborhoods centered at the codopants and include their first nearest neighbors. These processes result in a reduction in the superexchange coupling which in turn causes an enhancement in the ferromagnetic coupling (FMC) among the magnetic dopants. The proposed FMC is demonstrated using ab initio calculations of the electronic properties of codoped ZnO, GaN and TiO2.
