Riou, Jean-Félix. „Etude des propriétés de propagation d'un laser à atomes“. Paris 11, 2006. https://pastel.archives-ouvertes.fr/tel-00138450.
Der volle Inhalt der QuelleThis thesis presents various experimental and theoretical aspects concerning a specific system of atom optics: the atom laser. In our experiment, this one results from a Bose-Einstein condensate of rubidium 87 and we thus initially detail the various cooling techniques used to obtain this coherent atomic source in a hybrid ferromagnetic trap. The atom lasers we produce are extracted from the condensed cloud by radiofrequency, and propagate vertically under the effect of gravity. One specificity of our setup lies in the strong magnetic confinement used, which results in non negligible collisional interactions between the laser and the condensed source. We show that this has an influence, not only on the atom laser coupling dynamics, but also on its propagation. We indeed observe a transverse structure containing caustics on the laser beam. By using methods initially developed for photonic optics (eikonal approximation, Fresnel-Kirchhoff integral, ABCD matrices), we calculate the atom laser wavefunction. Moreover, we characterize the matter wave propagation in the paraxial regime by using the beam quality factor M2. We finally report the realization of an atom laser, guided by a horizontal optical potential, which enables us to cancel the acceleration due to gravity in such way, that the De Broglie wavelength remains constant throughout propagation

Der volle Inhalt der QuelleWe studied the structure obtained by application of an electric or a magnetic field on suspensions constituted of submicronic particles. This reversible aggregation results from the polarization of the particles and thus depends on contrast of the permittivity or permeability between the suspending liquid and the particles. The formed structure will depend on the value of l, the ratio between dipolar and thermal energies. If l is higher than one, the dipolar force dominates, the particles form fibrils parallel to the field. This change of structure results in an evolution of the angular distribution of the light scattered by the suspension. By means of these characteristics, it is possible to determine the distribution of sizes of the chains and the distance between particles inside chains simultaneously. By introducing a repulsive force, estimated from the evolution of the distance versus the electric field, we obtain a good agreement between the theoretical and experimental sizes at high frequency. On the other hand at low frequency, they differ from several orders of magnitude. The structures formation kinetic is experimentally slower than that predicted b theory. The other part of this thesis concerns the study of phase separation of a magnetorheological suspension (transition from chains to columns). The theoretical model where the distance between the particles is an adjustable parameter allows to predict accurately the critical values of the concentration and of the parameter l. However the shapes of the experimental and theoretical phase diagrams are rather different

Der volle Inhalt der QuelleIn this thesis we study the existence of a travelling wave solutions for an integro-differential system of equations from evolutionary epidemiology. We use ideas from dynamical system ideas theory coupled with estimates of the asymptotic behaviour of profiles. We prove that the wave solutions have a rather simple structure. This analysis allows us to reduce the infinite dimensional travelling wave profile system of equations to a four dimensional ODE system. The latter is used to prove the existence of travelling wave solutions for any wave speed larger than a minimal wave speed c?, provided that the epidemic threshold R0, which is expressed as a function of the principal eigenvalue of a certain integral operator, is strictly greater than 1. This same threshold condition is also used to prove that any travelling wave connects two determined stationary states. In the second part, we study the propagation properties of the solutions for the same spatially distributed system of equations, when the initial density of infected plants is a compactly supported function with the space variable x. When R0 > 1, we prove that spreading occurs with a definite spreading speed that coincides with the minimal speed c? of the travelling wave solutions discussed in the first part. Moreover, the solution of the Cauchy problem asymptotically converges to some specific function for which the moving frame variable x and the phenotype one y are separated

Der volle Inhalt der QuelleDuring the detection of nonlinear phenomena in solids, under the non-destructive evaluation by ultrasound, nonlinearities of piezoelectric ceramics might introduce parasitic effects that could disrupt the measurements. The objective here is to characterize the nonlinear properties of these ceramics and predict their influence on the propagation of ultrasonic waves. A method to characterize nonlinear properties based on the analysis of the generation of second harmonic on a piezoelectric resonator is developed here. It is shown that the analysis of the distortions for a wide range of excitation frequencies, allow to distinguish different sources of nonlinearity. Thereafter, the influence of an acoustic load on the nonlinear behaviour of vibration is studied. Finally, the previous results are used to predict the influence of non-linearity of piezoelectric ceramic on the propagation of acoustic waves in an environment outside
