Texto completo da fonteWe are concerned with Schrödinger and wave equations, both linear and non linear, in exterior domains. In particular, we are interested in the so-called Strichartz estimates, which are a family of dispersive estimates measuring decay for the linear flow. They turn out to be particularly useful in order to study the corresponding non linear equations. In non-captive geometries, where all the rays of geometrical optics go to infinity, many results show that Strichartz estimates hold with no loss with respect to the flat case. Moreover, the local smoothing estimates for the Schrödinger equation, respectively the local energy decay for the wave equation, which are another family of dispersive estimates, are known to fail in any captive geometry. In contrast, we show Strichartz estimates without loss in an unstable captive geometry: the exterior of many strictly convex obstacles verifying Ikawa's condition. The second part of this thesis is dedicated to the study of the long time asymptotics of the corresponding non linear equations. We expect that they behave linearly in large times, or scatter, when the domain they live in does not induce too much concentration effect. We show such a result for the non linear critical wave equation in the exterior of a class of obstacles generalizing star-shaped bodies. In the exterior of two strictly convex obstacles, we obtain a rigidity result concerning compact flow solutions, which is a first step toward a general result. Finally, we consider the non linear Schrödinger equation in the free space but with a potential. We prove that solutions scatter for a repulsive potential, and for a sum of two repulsive potentials with strictly convex level surfaces. This provides a scattering result in a framework similar to the exterior of two strictly convex obstacles

Texto completo da fonteThe turbulence in thermonuclear fusion plasma can lead to increase of the plasma transport coefficient that enhances the particles and energy losses therefore deteriorates the plasma confinement. That is why measurements of the plasma turbulence is important for description of the plasma transport processes. Microwave plasma diagnostics is an efficient kind of the active plasma diagnostics to characterize the turbulence. Their principles are based on the collection of information integrated over the probed plasma volume, and printed on the reflected or scattered waves reaching the detector, for which interpretative models are required to extract the turbulence properties. The radial correlation reflectometry (RCR) and the Doppler reflectometry are widely used technics that provide information on plasma turbulence characteristics. The Collective Thomson Scattering (CTS) is a valuable microwave diagnostic that can give the information about such plasma parameters as the bulk ion temperature, bulk ion composition, the fast particles (alpha particles or ions of a heating beam) velocity distribution. The knowledge of the alpha particle velocity distribution is especially interesting and important to evaluate the ITER performance where the energy amplification of plasma heating power Q is expected to achieve the value about 10. The actual data analysis of the microwave diagnostics, or interpretations of a measured signal is fulfilled assuming a smooth Gaussian probing beam. It was demonstrated that the microwave beams can be significantly distorted due to the edge plasma turbulence, that may lead to misleading interpretations of the diagnostic signal, based on the microwaves, so the diagnostics interpretative models should be analyzed taken into account to the probing beam distortion. The improvement of the microwave diagnostics interpretative models is the main object of the study presented in this thesis.The aim of this PhD work is to include these missing effects in an interpretative model for CTS using X-mode probing beam
Pham, Truong Xuan. "Peeling et scattering conforme dans les espaces-temps de la relativité générale". Thesis, Brest, 2017. http://www.theses.fr/2017BRES0034/document.
Texto completo da fonteThis work explores two aspects of asymptotic analysis in general relativity: peeling and conformal scattering.On the one hand, the peeling is constructed for linear and nonlinear scalar fields as well as Dirac fields on Kerr spacetime, which is non-stationary and merely axially symmetric. This generalizes the work of L. Mason and J-P. Nicolas (2009, 2012). The vector field method (geometric energy estimates) and the conformal technique are developed. They allow us to formulate the definition of the peeling at all orders and to obtain the optimal space of initial data which guarantees these behaviours. On the other hand, a conformal scattering theory for the spin-n/2 zero rest-mass equations on Minkowski spacetime is constructed. Using the conformal compactifications (full and partial), the spacetime is completed with two null hypersurfaces representing respectively the past and future end points of null geodesics. The asymptotic behaviour of fields is then obtained by solving the Cauchy problem for the rescaled equation and considering the traces of the solutions on these hypersurfaces. The invertibility of the trace operators, that to the initial data associate the future or past asymptotic behaviours, is obtained by solving the Goursat problem on the conformal boundary. The conformal scattering operator is then obtained by composing the future trace operator with the inverse of the past trace operator

Texto completo da fonteWhispering galery mode resonators are dielectric cavities that support modes with ultra-high quality factor and small volume that remain confined in their inner periphery for time duratioons that can be as long as few microseconds. The strong confinement of these modes for such long durations strongly enhances nonlinear effect suchs as Kerr effect or Brillouin effect. These resonators can therefore be used for several applications such as spectroscopy, telecommunications or microwave generation. The objective of this thesis is to use Kerr and Brillouin nonlinearities in these resonators at the laser wavelength of 1550 nm, in order to generate high spectral purity microwave signals with frequencies rangong fros 5 to 30 GHz. The first chapter oh the thesis intriduces the theory, fabrication, coupling and characterisation of whispering gallery mode resonators. The second chapter is about the generation of Kerr optical frequency combs in these resonators and their application to the generation of microwave signals. We present our experimental resuktsdn the numerical modelling of Kerr combs, the analysis of oscillatory instabilities (due to thermal effect) observed during our experiments, and conclue. The third chapter concerns photon-phonon interactions via stimulated Brillouin scattering in these resonators and their application to the generation of microwave signals. We present our experimental results and the temporal model that we developed to track the dynamics of the forward and backscattered fields. The last chapter conclude the thesis. The research presented in this thesis has benne funded by the European Research Council through the project Nextphase
