Dynamics of fluids and transport applied to the early Earth
We have studied the heat and mass transfer during the early Earth history at multiple scales and for multiple systems by means of numerical computing. Two different... -
Sums and extremes in statistical physics and signal processing : Convergence ...
This thesis has grown at the interface between statistical physics and signal processing, combining the perspectives of both disciplines to study the issues of sums... -
Contribution to the study of mechanical properties of nuclear fuel : atomisti...
Mechanical properties of nuclear fuel are a complex problem, involving many coupled mechanisms occurring at different length scales. We used Molecular Dynamics models... -
Instabilité de Faraday dans les fluides complexes
Since Faraday's founding work in 1831, it is known that the surface of a vertically vibrated fluid layers undergoes the Faraday instability when the forcing... -
Spatial structure of complex network and diffusion dynamics
In the recent development of network sciences, spatial constrained networks have become an object of extensive investigation. Spatial constrained networks are embedded... -
Diffusion Moléculaire d'un dopant hydrosoluble dans une phase lamellaire lyot...
We studied the diffusion properties of an hydrophilic molecular probe in a lyotropic lamellar phase which is a strongly anisotropic medium. Two behaviours are observed... -
Synthesis, Study of Ferroelectricity, Superconductivity and Nonlinear optics ...
The growing studies of potassium dihydrogen phosphate (KDP) crystals have been the interest of researchers thanks not only to their unique nonlinear optical,... -
Nonperturbative renormalization group approach to polymerized membranes
In this thesis, we study the long-range behaviour of polymerized membranes using a non-perturbative renormalization group (NPRG) approach. We start by presenting the... -
Solid phase transitions induced by direct compression : the case of caffeine ...
The purpose of this study was to improve the understanding of process induced transformations (PITs) in the field of the pharmaceutical industry. This present study is... -
Variational and topological methods for the study of nonlinear models from re...
This thesis is devoted to the study of nonlinear models from relativistic quantum mechanics.In the first part, we show thanks to a shooting method, the existence of... -
Statistical analysis of networks and biophysical systems of complex architecture
Complex organization is found in many biological systems. For example, biopolymers could possess very hierarchic structure, which provides their functional... -
Mechanisms of magnetic nanoparticles capture : application to water purification
Magnetic separation is used in the domain of water purification. In these systems, functionalized or bare magnetic nanoparticles are used to capture a target pollutant... -
A study of the transition between quark gluon plasma and hadronic matter in a...
The quark and gluon plasma (QGP) is a state of matter observed in the collision of heavy ions in accelerators such as the LHC. It is formed at high temperature and /... -
Categorial Changes and Phase Transition : Perceptual Categories as Attractors
This thesis gets into the main question of Categorial Change in Perception and proposes a Dynamical approach that relies on the Catastrophes Theory and the model of... -
Thermal and superfluid properties of the two-dimensional Bose gas
The physical properties of a homogeneous system at the thermodynamic equilibrium are strongly constrained by its dimensionality. In this respect, the two dimensional... -
Theoretical study of the α<->γ cerium phase transition : including strong cor...
The isostructural phase transition of cerium has been and remains the aim of many studies in order to test methods developed to describe strongly correlated...
