Повний текст джерелаAmong the open problems of modern physics, dark matter (DM) is one of the most fascinating. It explains several gravitational anomalies observed at different scales: the flatness of rotation curves of spiral galaxies, the dynamics of galaxy clusters, the distribution of large-scale structures in the Universe, and the anisotropies in the temperature of the cosmic microwave background. Precise measurements of the latter, possibly combined with other techniques, show that DM constitutes about a quarter of the Universe's energy budget. Although we have reliable observational evidence of DM's existence, its nature remains a mystery, as no observation has yet shown that DM can interact with ordinary matter other than gravitationally. Numerous hypotheses about its nature remain. DM could exist as elementary particles not included in the Standard Model of particle physics, or as macroscopic compact objects such as primordial black holes (PBH). To reveal the nature of DM, or to rule out hypotheses concerning it, several observational techniques are available. In this thesis, we focus on the method of indirect detection, which involves looking for signals of the annihilation or decay of DM in the form of charged cosmic rays, photons or neutrinos. Each product carries different types of information. Photons and neutrinos, being neutral particles, can propagate without being deflected by the surrounding magnetic fields, making it easier to trace their source of emission. Charged cosmic rays, on the other hand, may consist of antimatter, which is less likely produced by astrophysical processes and can therefore be detected with a low background. In this thesis, we study the emission of secondary photons by the interaction of DM products with the galactic environment. Specifically, we consider the case in which DM is a particle with a mass below a GeV. The electrons and positrons produced could interact with ambient photons in the galaxy, producing X-rays through inverse Compton scattering. The prediction of the spectrum of this radiation, compared with data from X-ray observatories, provides strong constraints on this type of DM. Similarly, we apply this same principle to the case of PBH evaporation in order to impose strong constraints on them

Повний текст джерелаThis thesis treats the detection of dark matter in sorne extensions of the Standard Model of particle physics. Dark matter (DM) is a new matter form whose existence was postulated in order to explain a series of cosmological observations that are in disagreement with current theories in particle physics and cosmology. The tirst chapter of this thesis briefly presents sorne basic elements which are indispensible when working on dark matter. Ln the second chapter, we discuss the potential DM detection modes and we present sorne original results concerning the capacity of the respective experiments to reconstruct some properties of dark matter candidates. Ln the third chapter, we describe a minimal solution to the dark matter problem. The Standard Model of particle physics is slightly extended to accomodate a particle that could constitute the missing mass of the universe and the phenomenology of this particle is studied. Ln the fourth chapter, we present a second solution to the dark matter problem, this time much less minimal or economical. The resulting models (which are called supersymmetric) are considerably more complicated. We study the phenomenology of two such examples. Finally, a summary and sorne conclusions form a fifth chapter. Three appendices follow, containing sorne technical elements as well as a certain number of points aiming at corroborating a few arguments given in the main text

Повний текст джерелаPremièrement nous proposons d'ajouter un terme d'amortissement avec la surface au modèle nanoplasma original de T.Ditmire et al. (1996). Nous comparons diverses observables expérimentales (xénon) et étudions l'évolution des états de charge avec la taille ou l'éclairement.
Deuxièmement nous proposons un modèle microscopique de dynamique moléculaire à trois dimensions robuste en l'absence d'excitation. L'émission électronique à 10^11 W/cm^2 (sodium) se compare à celle obtenue par d'autres modèles tels que le modèle VUU-LDA. Les électrons de coeur sont émis à partir de 5 10^15 W/cm^2. Les événements rares sont accessibles et nous montrons que l'explosion ionique de type coulombien est autosimilaire (10^16 W/cm^2). Enfin, l'émission électronique (gaz rare) est comparée avec le modèle nanoplasma.

Повний текст джерелаThe Herschel Space Observatory satellite has permitted to detect light in the far infrared, corresponding to frequencies at which molecules emit light through rotational transitions. ALMA, an interferomete rlocated on the Chilean desert of Acatama took over Herschel and will allow new observations of cold molecular clouds with an accurate angular accuracy. ALMA observes in the range of millimeter andsub-millimeter which makes it complementary to the Satellite Herschel (far infrared). These significant advances in observing particle interactions at the microscopic level, to produce and trap diatomic molecules in specific internal states, open new perspectives in the field of collision physics and theoretical chemistry.Observation of interstellar molecules has benefited from advances in astronomy, to identify vibrational rotational ransitions of molecules. Furthermore, spectroscopic data provide us with important information on the state of the interstellar medium: ionized or neutral.The cation methylidene CH + was observed in the diffuse medium through its X1Σ + -A1Π electronictransition. It plays an important role in the different stages of the complex chemical behaviour through processes and molecular reactions that occur in interstellar and circumstellar regions. So CH+ launches large chain chemical processes that can progress to the formation of more complex species.The fine structure transition of C +; is the strongest emission line of the Milky Way. The C + ion is atracer of density and temperature in diffuse clouds and regions dominated by photons (PDR). The C +line is an important tool to probe the gas content and star formation processes in the Milky Way andother galaxies.C+ + H2 collisions can lead to the formation of CH +. This reaction has been extensively studied theoretically and experimentally, however, it is endothermic by 3211cm-1 and at the typical temperatures for MIS and H2 in its ground vibrational state, the reaction does not occur. The only process is then the C + spin-orbit excitation process.Spin orbit relaxation C + (2P1 / 2) + H 2 (v j) = C + (2P3 / 2) + H 2 (v0; j0) which was first studied inthis thesis contributes to the cooling of the gas constituting the interstellar clouds.The vibrational excitation of H2 (v> 0), which takes place during collisions with C + has a significant influence on the abundance of CH +. CH + is a highly reactive ion, it is destroyed by the abstractionreaction of hydrogen that has been considered in this work. It is therefore interesting to accurately assess the effectiveness of this path of destruction. The dilemma is that this ion is also abundantly found in the neutral and cold environment.This thesis focuses on the inelastic and reactive collisions studies of interstellar interest. We used ab initio highly correlated methods to tackle the electronic structure parts. Moreover, the nuclear dynamics of the systems was studied using a time independent quantum formalism, based on the Jacobi coordinates in the case of the spin-orbit excitation of C + (2P) + ortho H2, and para-H2 and rotational excitation of (+ CD) + He, or the hyper spherical coordinates for the reactive process in the case of the abstraction of a hydrogen in H + CH +.Our concern was to give a comprehensive basis of the mechanisms and provide a quantification of the effective spin-orbit relaxation cross sections and reaction rates to confront with spectroscopic observations. The new rate constants we obtained should help to better interpret the observations of C+ radiation emissions obtained by current and future telescopes

Повний текст джерелаIn this thesis, we are mainly interested in three topics : functional inequalities and their probabilistic aspects, hydrodynamic limits for interacting continuous spin systems and discretizations of stochastic differential equations. This document, in addition to a general introduction (written in French), contains three parts. The first part deals with functional inequalities, especially logarithmic Sobolev inequalities, for canonical ensembles, and with hydrodynamic limits for continuous spin systems. We prove convergence to the hydrodynamic limit for several variants of the Ginzburg--Landau model endowed with Kawasaki dynamics, with quantitative bounds in the number of spins. We also study convergence of the microscopic entropy to its hydrodynamic counterpart. In the second part, we study links between gradient flows in spaces of probability measures and large deviations for sequences of laws of solutions to stochastic differential equations. We show that the large deviations principle is equivalent to the Gamma--Convergence of a sequence of functionals that appear in the gradient flow formulation of the flow of marginals of the laws of the diffusion processes. As an application of this principle, we obtain large deviations from the hydrodynamic limit for two variants of the Ginzburg-Landau model. The third part deals with the discretization of stochastic differential equations. We prove a transport-Entropy inequality for the law of the explicit Euler scheme. This inequality implies bounds on the confidence intervals for quantities of the form $\mathbb{E}[f(X_T)]$. We also study the discretization error for the evaluation of transport coefficients with the Metropolis-Adjusted Langevin algorithm (which is a combination of the explicit Euler scheme and the Metropolis algorithm)
