Friction coefficient of atoms near a metal surface - The friction coefficient α of an atom moving near a metal surface and that of two interacting adatoms is calculated by using a Newns-Anderson hamiltonian. In the absence of Coulomb interaction, it is found convenient to decompose α into (∇ηv)2 and sin2 (η v - ηv') terms where the η v's are the generalized phase shifts at Fermi level. For one atom, α is evaluated numerically in a simple model. The origin of the sharp maxima reported by other authors is clarified. The Coulomb interaction is then taken into account, first within the Hartree-Fock approximation. The latter appears to be little valuable, especially near the onset of the localized magnetism. In the case of one atom, treated in a simple model, an exact expression of α in terms of the density of states at the atom is derived, leading to a more precise picture of the behaviour of α. Finally, the respective role of electronic excitations and phonons in friction is discussed.

Simple pairing picture of (2 × 1) instability and reconstruction of silicon surfaces - The (2 x 1) reconstructions of three typical silicon surfaces, namely (111), (110) and (100), are described within a very simple pairing picture, relating mutual saturation of Shockley surface states (dangling bonds) from the Fermi energy EF to the geometrical instability of ideal (1 x 1) surfaces. The mechanism involved is the electron-phonon coupling (assumed to be stronger at the surface than in the bulk) between surface states and the deformation modes η and contains two other important tools : the pairing theorem relating wave functions and energies of surface states differing by a certain wave vector κ, and the selection rule picking out reconstruction modes allowed by the present theory. The formalism utilized is applicable also to the interaction of electrons with other boson fields (excitons, plasmons, paramagnons).

– Oleksandr Motornyi , Ab initio study of electronic surfaces states and plasmons of gold : role of the spin-orbit coupling and surface geometry. - Cette thèse de doctorat est dédiée à l’étude, avec des méthodes de calcul ab initio, desplasmons de surface et des états de surface de surfaces d’or, plate ou comportant desmarches (surface vicinale), par la simulation numérique de spectres de perte d’énergieélectronique (EEL) au moyen de la théorie de la fonctionnelle de la densité (DFT) et de lathéorie de perturbation de la fonctionnelle de la densité dépendant du temps (TDDFPT).L’influence du couplage spin-orbite (CSO) et celle de la géométrie de la surface ont étéétudiées. Dans l’or cristallin, j’ai étudié l’effet des électrons de semicoeur sur les spectresEEL à q = 0. J’ai montré en particulier que pour produire un spectre EEL sur une largegamme de fréquences, de 0 à 60 eV, il est nécessaire de tenir compte des électrons desemicoeur dans le pseudopotentiel, et qu’ils peuvent néanmoins être gelés dans le coeurpour l’étude de la partie basse en énergie du spectre EEL, pour des énergies inférieures à
