Disordered systems are ubiquitous in nature and their study is complicated and often leads to controversial results. In any case, the important role of such systems in science and technological applications should not be ...
As the evolutionary end-point of most main-sequence stars, white dwarfs can be used to infer important properties concerning the formation and evolution of the different Galactic stellar populations. Population synthesis ...
Metalloprotein are proteins containing metal ion cofactors. Compared to chemical catalysts, metalloproteins have a well-defined configuration around the active site which ensures higher specificity, selectivity and reaction ...
The aim of this thesis is to deepen into the understanding of the mechanisms responsible for the generation of complex and stochastic dynamics, as well as emerging phenomena, in the human brain. We study typical features ...
Optical excitable systems that mimic neuronal behavior have potential to be building-blocks of novel, ultra-fast, neuron-inspired photonic information processing systems. In particular, semiconductor lasers with optical ...
The brain is known to operate under the constant influence of noise arising from a variety of sources. It also organises its activity into rhythms spanning multiple frequency bands. These rhythms originate from neuronal ...
Dynamical instabilities which lead to spontaneous pattern formation are present in a wide variety of nonlinear dynamical systems, both in nature as well as in technological areas. The instabilities may be saturating, leading ...
Recent advancement in Photonics have brought about a new era of miniaturisation. Along came a need for technology to allow the manipulation of light at the micrometer scale, with precise control over beam propagation. The ...
The main objective of the thesis is to study static and/or dynamic properties of a set of quantum fluids by means of quantum Monte Carlo techniques, mainly using the path integral formalism to obtain results both at zero ...
The PhD project, entitled "Second harmonic generation in disordered nonlinear crystals: application to ultra-short laser pulse characterization", is devoted to the study of second harmonic generation in nonlinear ferroelectric ...
This thesis focuses on the thermodynamic and crystallographic characterization of C60 solvates formed with small organic molecules (CBr2(CH3)2, CBr2Cl2, CBr2H2, CBrCl2H and CBrClH2) Chapter I provides an introduction ...
Control is important for transferring theoretical scientific knowledge into practical technology for applications in numerous fields. This is why coherent control study is significant on every timescale to have a complete ...
By 2050 the energy consumption is expected to increase considerably.The production might be mostly based on renewable energy mix driven by the nuclear fusion which could potentially deliver continuous, large-scale power ...
The PhD thesis "Desarrollo y aplicación de herramientas de valoración de riesgos tecnológicos en centrales nucleares españolas a partir de la técnica de Análisis Probabilista de Seguridad” results from the research projects ...
The quest for new artificial structures and materials uncovers novel new light-matter interactions, and intriguing physical phenomena. Since the late 80’s purely dielectric materials have been structured, at the wavelength-scale, ...
Shorelines around the world are rarely smooth and they can present undulations and cuspate shapes. On the one hand, human actions can cause shoreline perturbations via beach nourishments, which in turn perturb the wave ...
The simulation and modelling of complex applications involving the interaction of processes governed by different physical principles is addressed in this thesis. The interaction of a fluid with a deformable body, or the ...
Glassy phases play an important role in our daily life and in many industries such as the food, pharmaceutical, and construction and are responsible for certain vital mechanisms in living species. Whereas crystals are solid ...
Precipitation is one of the most important, and also difficult to predict, elements of climate. This difficulty is associated with the transport of moisture through weather fronts that change their pathway, shape and ...
The occurrence of heat waves and cold spells has received special attention in recent years due to their impact on human health, ecosystems and economy. In the context of climate change, there is evidence that extreme ...
