Texte intégralIn 1848, Edmond Becquerel proposed one of the first techniques of color photography. This technique raised a long-standing debate in the scientific community concerning the origin of the observed colors. In 2019, Victor de Seauve, during his thesis at the Muséum National d'Histoire Naturelle in Paris, could clarify some important issues, proposing a new explanation. The aim of the present thesis was to participate in this effort of comprehension, by adding theoretical insight. The first question is which level of theory one may adopt in order to correctly describe the electronic and optical properties of AgCl. Our calculations show that only the solution of the Bethe-Salpeter equation is able to describe the optical spectrum of AgCl, since the spectrum is dominated by a strong peak at the absorption onset, due to a bound exciton. Moreover, the calculation has to be based on a band structure that results from a self-consistent GW calculation. In order to make the Bethe-Salpeter calculations possible, a previously proposed model dielectric function was used in an improved way. Our results well describe the measured absorption spectra, and enable us to analyse and interpret the observations. In the hypothesis brought forward by the team at the Museum, the light excites a silver nanoparticle, followed by a transfer of charge at the interface between the nanoparticle and AgCl. In order to be able to study this phenomenon, we have developed a numerical approach describing the charge dynamics due to an external perturbation. In particular, this approach has allowed us to show that a bound exciton influences the charge dynamics significantly. Finally, we have set up a first model meant to simulate the charge transfer between a silver nanoparticle and AgCl, based on a simplified heterostructure. We have shown how the absorption spectrum of AgCl changes due to its neighbourhood to the silver metal, and how these changes can be described by the effective medium theory. Calculations of the density induced by a periodic perturbation have been carried out. These calculations remain cumbersome, and the study will continue with the idea to combine ab initio calculations with effective medium theory

Texte intégralNowadays, charge-exchange excitations in nuclei become one of the central topics in nuclear physics and astrophysics. Basically, a systematic pattern of the energy and collectivity of these excitations could provide direct information on the spin and isospin properties of the in-medium nuclear interaction, and the equation of state of asymmetric nuclear matter. Furthermore, a basic and critical quantity in nuclear structure, neutron skin thickness, can be determined indirectly by the sum rule of spin-dipole resonances (SOR) or the excitation energy spacing between the isobaric analog states (lAS) and Gamow-Teller resonances (GTR). More generally, charge-exchange excitations allow one to attack other kinds of problems outside the realm of nuclear structure, like the description of neutron star and supernova evolutions, the β-decay of nuclei which lie on the r-process path of stellar nucleosynthesis, and the neutrino-nucleus cross sections. They also play an essential role in extracting the value of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element Vud via the nuclear 0+→ 0 + superallowed Fermi β decays. For all these reasons, it is important to develop the microscopic theories of charge-exchange excitations and it is the main motivation of the present work. Ln this work, a fully self-consistent charge-exchange relativistic random phase approximation (RPA) based on the relativistic Hartree-Fock (RHF) approach is established. Its self-consistency is verified by the so-called lAS check. This approach is then applied to investigate the nuclear spin-isospin resonances, isospin symmetry-breaking corrections for the superallowed β decays, and the charged-current neutrino-nucleus cross sections. For two important spin-isospin resonances, GTR and SOR, it is shown that a very satisfactory agreement with the experimental data can be obtained without any readjustment of the energy functional. Furthermore, the isoscalar mesons are found to play an essential role in spin-isospin resonances via the exchange terms, which leads to a profound effect in the nuclear isovector properties, e. G. , the density dependence of the symmetry energy in nuclear matter. Ln the investigation of the isospin symmetry-breaking corrections for the superallowed β decays, it is found that the corrections δc are sensitive to the proper treatments of the Coulomb mean field, but not so much to specific effective interactions. With these corrections δc, the nucleus-independent Ft values are obtained in combination with the experimental ft values in the most recent survey and the improved radiative corrections. The values of Cabibbo-Kobayashi-Maskawa matrix element IVudI thus obtained weil agree with those obtained in neutron decay, pion decay, and nuclear mirror transitions, while the sum of squared top-row elements somehow deviates from the unitarity condition. Expressing the weak lepton-hadron interaction in the standard current-current form, the relevant transitions from the nuclear ground state to the excited states are calculated with RHF+RPA approach. Ln this way, the semileptonic weak interaction processes, e. G. , neutrino reactions, charged- lepton capture, β-decays, can be investigated microscopically and self-consistently. First illustrative calculations of the inclusive neutrino-nucleus cross section are performed for the 16 O(Ve ,e-)16 F reaction, and a good agreement with the previous theoretical studies is obtained. The main effort is dedicated to discussing the substantial influence of different recipes for the axial vector coupling strength and the theoretical low-Iying excited states of the daughter nucleus
Tegomo, Chiogo Bodry. « Spectroscopic studies of cerium and Ytterbium-based Kondo systems ». Electronic Thesis or Diss., Université de Lorraine, 2022. http://www.theses.fr/2022LORR0193.
Texte intégralCerium and ytterbium compounds are systems that exhibit outstanding magnetic, electronic, and thermodynamic properties at low temperatures, such as the Kondo effect, heavy fermions, intermediate valence, and charge density waves. These properties are due to the very strong electron-electron interactions of the f states and the hybridization of the f states with the conduction electrons. In the first part of this thesis work, we investigate the temperature-dependent electronic structure of YbPd, a Kondo mixed-valent cubic compound at high temperature, which exhibits incommensurate and commensurate charge-density-wave (CDW) ordering below T_1 = 130 K and T_2 = 105 K, respectively. Below 105 K, magnetic Yb^{3+} and nonmagnetic Yb^{2.6+} are arranged alternatively along the c axis, in a tetragonal structure exhibiting valence order. Hard x-ray photoemission spectroscopy of Yb 3d states show temperature-independent Yb^{2+} and Yb^{3+} features indicating single-Yb site dynamic valence fluctuations above T_1, and a clear temperature dependent valence change of the two crystallographic Yb sites in the CDW phase. Simplified single-impurity Anderson model calculations of the Yb 3d states show good agreement with the temperature-dependent valency change and provide site-dependent Kondo temperatures. The results indicate an evolution from dynamic mixed-valence in the cubic phase to long-range static CDW order in the tetragonal phase, which is driven by the difference in Kondo energies of the two phases. Resonant inelastic x-ray scattering (RIXS) is a very efficient technique to study elementary excitations in a large variety of systems, such as charge transfer excitations, the crystal field, and spin-orbit excitations. In the second part of this work, we investigated cerium compounds with different Kondo temperatures using RIXS at Ce M_5-edge combined with simulation using the full multiplet theory and the single impurity Anderson model. We demonstrated that all the charge excitations observed in combined photoemission and inverse photoemission can be evidenced by RIXS spectroscopy just by varying the incident photon energy around the Ce M_5-edge. We also discuss the drastic polarization dependence of the f^0 structure in RIXS spectra and the strong temperature dependence of the fluorescence-like structure, which is reminiscent of the temperature dependence of the Kondo resonance
