We performed a first-principles study of the structural, vibrational, electronic, and magnetic properties of NaMnF3 under applied isotropic pressure. We found that NaMnF3 undergoes a reconstructive phase transition at 8 GPa from the Pnma distorted perovskite structure toward the Cmcm postperovskite structure. This is confirmed by a sudden change of the Mn-F-Mn bondings where the crystal goes from corner-shared octahedra in the Pnma phase to edge-shared octahedra in the Cmcm phase. The magnetic ordering also changes from a G-type antiferromagnetic ordering in the Pnma phase to a C-type antiferromagnetic ordering in the Cmcm phase. Interestingly, we found that the high-spin d-orbital filling is kept at the phase transition which has never been observed in the known magnetic postperovskite structures. We also found a highly noncollinear magnetic ordering in the Cmcm postperovskite phase that drives a large ferromagnetic canting of the spins. We discuss the validity of these results with respect to the U and J parameters of the GGA+U exchange-correlation functional used in our study and conclude that large-spin canting is a promising property of the postperovskite fluoride compounds.

Thermoelectricity has been regarded as one of the most promising strategies for clean, low-cost and environmental friendly sustainable energy for several decades. Perovskite oxides, like SrRuO3, are considered as a potential thermoelectric material for low-cost and large-scale thermoelectric applications due to their good thermal and chemical stability in a wide temperature range, great flexibility for structural and compositional manipulating, and environmental friendliness. This thesis is devoted to a theoretical study of the lattice dynamics and thermoelectric properties of materials, like SrRuO3 perovskite and MgAgSb-based materials. Firstly, to obtain insight into the lattice dynamics of the SrRuO3, the phonon-related properties are presented and contributes to rationalize better why many ABO3 perovskites, including metallic compounds, exhibit an orthorhombic ground state. Then the thermoelectric properties of SrRuO3 are investigated by combining first-principles calculations and Boltzmann transport theory, revealing the relationship between the exchange-correlation functionals and the thermoelectric quantities. Furthermore, based on the first-principles calculations, effective model potentials for SrRuO3 are constructed providing access to the finite-temperature properties and phase-transitions. Additionally, the electronic structure and thermoelectric properties of a class of new emerging MgAgSb-based materials, which are promising for room-temperature thermoelectric applications, are also studied and the optimization strategies are proposed for the improvement of thermoelectric performance.

This paper analyzes an overlapping generation (OLG) growth model wherein saving finances second period consumption and bequest-as-consumption. First, it looks at the market equilibrium and at the optimal solution; then it turns to the issue of decentralizing the optimal solution with various taxes and transfers. Depending on the available instruments, either a first-best or a second-best optimum can be achieved. Throughout the paper, the results are contrasted with those obtained in the standard OLG model without intergenerationel transfers. [less ▲]

La fiscalité constitue un champ d’investigation qui impacte le territoire de multiples manières. Le financement des communes de Wallonie s’appuie sur différentes sources de recettes, dont la fiscalité constitue la plus importante. En 2011, elle représentait près de 48% des recettes globales des communes wallonnes. [less ▲]

Cette recherche consiste en une réflexion sur la fiscalité en tant qu'outil d'aménagement du territoire et en tant que moyen de recontrer les défis du développement territorial, dans le contexte wallon. Elle s'intègre dans le contexte des débats qui entourent la sixième réforme de l'Etat belge. Elle a pour objectif l'établissement d'un cadre utilisable pour l'évaluation de certains effets territoriaux suite à la mise en oeuvre ou à la modification de politiques fiscales. In fine, elle aboutira à des propositions d'adaptation ou de mise au point de nouvelles mesures en vue de rencontrer les défis territoriaux. Afin d'atteindre ces objectifs, elle se concentre également sur la mise en évidence des liens existants entre le système fiscal en place et certains défis territoriaux. Son objet est restreint au logement et à l'aménagement en lien avec le logement. [less ▲]
