Full textRadio-frequency (rf) traps allows one to confine charged particles (atoms or molecules) in a small region of space. These traps, with laser cooling technics, allows one to study and to control matter at the atomic level.In this thesis are shown different results obtained by numerical simulations using molecular dynamics technics. This thesis is formed of four parts. A first part introduce the necessary knowledge to comprehend the ion dynamics in rf traps. The second part present the results from a study on the influence of coulomb coupling on the doppler cooling of trapped ions in a linear quadrupole rf trap. The third part is a study of the properties of ring structures of ions, obtained for low temperatures in linear higher order rf traps. A last part of the thesis is a proposal allowing one to obtain additional rf field-free regions in linear higher order rf traps

Full textTrois expériences sont décrites dans cette thèse. Dans la première, la caractérisation du régime de collisions élastiques dans un piège hybride optique et magnétique a été menée. Cette étude est d'une grande importance pour évaluer, dans un tel piège, les possibilités d'atteindre la phase quantique de condensation de Bose-Einstein pour l'atome de césium. Dans la deuxième expérience, un dispositif de piégeage dipolaire de molécules de césium, réalisé à l'aide d'un laser CO2, a permis d'obtenir un échantillon dense et froid de molécules, créées par photoassociation d'atomes froids. Le confinement d'atomes et de molécules a été mis en évidence et des études quantitatives de collisions froides inélastiques molécule-atome ont pu être réalisées. Une mesure de ce taux de collisions est donnée dans le manuscrit. Nous abordons, dans la troisième expérience, l'étude détaillée des phénomènes d'interactions à longue distance dipôle-dipôle qui règnent au sein d'un gaz d'atomes de Rydberg froids. Ces interactions ont été mises en évidence et caractérisées à l'aide d'une méthode originale de spectroscopie optique de haute résolution.

Full textThis thesis is dedicated to the study of the dynamical properties of various systems of interacting random walkers. In the first part of this manuscript, we study a model of self-gravitating Brownian particles. In this model, the particles evolve at fixed temperature. This corresponds to a canonical description of self-gravitating systems. When the temperature is above a certain critical temperature, metastable equilibrium states exist. By contrast, below this critical temperature, the system collapses and forms a Dirac peak. It has been shown that the model of self-gravitating Brownian particles shares numerous analogies with the chemotaxis of biological populations. In this thesis, we generalize these results to the multi-component case, in which the particles can have different masses. In addition, we study the phase transitions between gaseous states and condensed states for a model of self-gravitating Brownian particles (or its biological analog) around a central body. Moreover, we show that the model of self-gravitating Brownian particles exhibits many analogies with the Bose-Einstein condensation of free bosons strongly coupled with a thermal bath. This model corresponds to a canonical description (fixed temperature) of the Bose-Einstein condensation. The coupling between a thermal bath and a system of free bosons induces a effective interaction between the bosons. This one forces them to condensate in their fundamental state when the temperature is less than a certain critical temperature. We then study the solutions of the bosonic Fokker-Planck equation of this problem which leads to the formation of a Dirac peak, modeling the condensate. In the second part of this thesis, we study the freely decaying two-dimensional turbulence. Two-dimensional turbulence has the striking property to generate a set of coherent structures called vortices. If the turbulent system evolves freely (without any external forcing), the turbulent fluid decays due to the merging processes of like-sign vortices. Some studies have shown that two-body merging processes are dominant for large vortex densities whereas there are inefficient at very low density: in this case, the evolution is dominated by three-body processes. .

Full textMachining of flexible pieces, hard machining and high-speed machining put in evidence the need to study the dynamic behavior of the process. In particular, it is necessary to treat the Vibrations associated to the cutting phenomenon. To do this, the elementary mechanical phenomena are first characterized and formulized, and then all of the elements participating in the process are considered as a whole. During a machining operation, vibrations are controlled a priori by a large number of variables such as the cutting parameters and the flexibility of the piece as well as that of the wool Behavior models to be introduced into CAO/CAM programs in order to predict this dynamic behavior are nonexistent. This is the general framework of the present research work. Its objective is to characterize the dynamic behavior of flexible pieces and tools during a turning operation. The search of a model allowing to predict the dynamic response is very complex due to the number of elements involved (piece, tool, cutting, machine-tool. . . ) and the cutting phenomena to be modeled. The response of the piece to be machined is given by calculation based on the Finite Element Method. The flexibility of the tool and of its support are also considered in order to built a global dynamic model Cutting phenomena are formalized from experimental results (COM). Stability criteria are thus deduced. Successive operations of turning at a thin-wall tube, boring of a thick-wall tube and boring of a thin-wall tube are considered in order to strengthen the model

Full textWith the increasing development of wireless networks of low-power sensors for the so-called internet-of-things, there is a need for efficient ways to ensure the energetic autonomy of sensing nodes. Among the various energy harvesting solutions, converting the abundant mechanical energy present in the environment into electrical energy is very promising. In this emerging field of research, ZnO nanowires (NWs) have been strongly studied during these last two decades, both as such, and integrated into nanocomposite materials. At the nanoscale, they feature improved electromechanical properties compared to bulk, as well as easy integration and manufacturing, on both rigid and flexibles substrates. However, some intriguing discrepancies between the experimental and simulation results available at the beginning of this PhD highlighted the need for a better understanding of the piezoelectric operation of NW-based composites, especially for what concerns two important aspects which had been poorly addressed so far: the coupling between piezoelectric and semi-conducting properties in simulations, and the dependence of electromechanical properties with ZnO NW growth method or with NW surrounding environment in experiments.From the theoretical point of view, this Ph.D. thesis studies the coupling of piezoelectric and semiconducting properties in ZnO NWs and related nanocomposites and provides optimization guidelines for mechanical to electrical transducing applications. It investigates the influence of doping level, free carrier density, interface traps and geometrical parameters on electromechanical parameters. Simulations of ZnO NW-based nanocomposites under mechanical compression were performed using the Finite Element Method (FEM). Experimentally, several atomic force microscopy (AFM) modes, such as piezoelectric force microscopy (PFM), Kelvin probe force microscopy (KPFM), and conducting atomic force microscopy (C-AFM) were used, in order to probe locally electrical and electromechanical parameters which play a key role in the efficiency of the piezoelectric response of ZnO NWs. Our results showed that doping level, free carriers and surface traps, as well as traps dynamics, must be considered in order to explain the amplitude and the potential asymmetry of the electromechanical response, or the influence that geometry has on it. They demonstrate that semiconducting properties should be taken into account for the analysis of experimental results and for the correct design of electromechanical self-powered devices based on ZnO NWs and nanocomposites
