Advances in classical and quantum wave dynamics on quasiperiodic lattices : a dissertation submitted for the degree of Doctor of Philosophy in Physics, Centre for Theoretical Chemistry and Physics, New Zealand Institute for Advanced Study, Massey University, Albany, New Zealand

Lattices and discrete networks are cornerstones of a number of scientific subjects. In condensed matter, optical lattices allowed the experimental realization of several theoretically predicted phenomena. Indeed, these structures constitute ideal benchmarks for light and wave propagation experiments involving interacting particles, such as clouds of ultra-cold atoms that Bose-Einstein condensate. Moreover, they allow experimental design of particular lattice topologies, as well as the implementation of several classes of spatial perturbations. For example, Anderson localization being observed for the first time in atomic Bose-Einstein condensate experiments and Aubry-André localization discovered with light propagating through networks of optical waveguide. This thesis considers different types of lattices in the presence of quasiperiodic modulations, mainly the celebrated Aubry-André potential. Particular attention will be given to spectral properties of models, localization features of eigenmodes and the transition from delocalized (metallic) eigenstates to localized (insulating) ones within the energy spectrum. We additionally discuss the relation between the model’s properties and the dynamics of particles hopping along the lattice. After introducing the linear discrete Schrödinger equation, we first discuss the spectral properties of the Aubry-André model. We then study the transition between metallic and insulating regimes of a class of quasiperiodic potentials constructed as an iterative superposition of periodic potentials with increasing spatial period. Next, we discuss the Aubry-André perturbation of flat-band topologies, their energy-dependent transition (mobility edge), which can be expressed in analytical forms in case of specific onsite energy correlations, highlighting existence of zeroes, singularities and divergences. We then discuss two cases of driven one-dimensional lattices, namely an Aubry-André chain with a weak time-space periodic driving and an Anderson chain with a quasiperiodic multi-frequency driving. We show anaytically and numerically how drivings can lift the respective localization and generate delocalization by design. Finally we discuss the problem of the possible generation of correlated metallic states of two interacting particles problem in one dimensional Aubry-André chains, under a coherent drive of the interaction

Die längsten Titel der Filmgeschichte : eine Liste

Eine Suche nach den längsten Titeln der Filmgeschichte erweist sich als recht mühsame Sammeltätigkeit. Ohne Hinweise von Freunden wäre vieles hier nicht genannt worden.

L’Orphée rouge : 750 av. J.-C.

« L’Orphée rouge » est placé sous l’égide d’une stèle de couleur ocre, représentant un prince qui danse à la porte de l’enfer où il a vaincu la mort. Différents artefacts, semblablement rattachés à des légendes et des rituels, sont étudiés par rapport à leur théâtralité : masques, partitions, pétroglyphes et sculptures. À l’aide d’études paléographiques récentes et de récits d’observateurs de l’époque, cet essai entend jeter un peu de lumière sur certaines « actions » des Premières Nations de la Nouvelle-France, leur déroulement, leurs lieux et leurs thèmes.« L’Orphée rouge », placed on an ochre coloured stele, represents a prince who dances at the door of hell where he has overcome death. Different artefacts, similarly linked to legends and rituals, are studied with regard to their theatricality: masks, partitions, petroglyphs and sculptures. Using recent paleographic studies and accounts of observers of the time, this essay intends to shed some light on certain "actions" of the First Nations peoples in New France

The ArDM project: a Dark Matter Direct Detection Experiment based on Liquid Argon

The Dark Matter part of the universe presumably consists of WIMPs (Weakly Interacting Massive Particles). The ArDM project aims at measuring signals induced by WIMPs in a liquid argon detector. A 1-ton prototype is currently developed with the goal of demonstrating the feasibility of such a direct detection experiment with large target mass. The technical design of the detector aims at ind ependently measuring the scintillation light and the ionization charge originating from an interaction of a WIMP with an argon nucleus. The principle of the experiment and the conceptual design of the detector are described.Comment: 4 pages, 1 figure, Invited talk at 2nd Workshop On TeV Particle Astrophysics, 28-31 August 2006, Madison, WI, US
