Villuendas Pellicero, Diego (Data de defensa: 2016-02-03)
The goal of this work is to investigate the magnetic deflagration phenomena in two very different magnetic systems, using two very different experimental techniques. In the first chapter of this dissertation I introduce ...
Lendínez Escudero, Sergi (Data de defensa: 2016-01-20)
Research in magnetic materials leads to new devices and technologies. As the technology progresses, the devices become smaller and this miniaturization allows more storage capacity and lower costs in the production of new ...
Casanova i Fernàndez, Fèlix (Data de defensa: 2004-03-09)
This Ph.D. Thesis has been devoted to the preparation and characterisation of bulk Gd5(SixGe1-x)4 alloys and to the study of the magnetocaloric effect at the first-order magnetostructural transition appearing in these ...
Fernández Sabater, Alberto (Data de defensa: 2008-11-13)
[spa] El objetivo de la presente tesis es el estudio de las subestructuras que aparecen a un nivel de resolución mesoscópico en las redes complejas. Dichas subestructuras, que en el campo de las redes complejas son denominadas ...
Reguera, D. (David) (Data de defensa: 2001-11-23)
Esta tesis está dedicada al estudio de la cinética de la nucleación centrada en sus aspectos mesoscópicos y fuera equilibrio. Hemos desarrollado y presentado un marco teórico, basado en la Termodinámica Mesoscópica y de ...
Pont i Pla, Oriol (Data de defensa: 2009-04-24)
Complex systems are abundant in our natural environment. In linear systems, the equations of their dynamics can be very difficult to solve, but if they cannot be described with a single characteristic scale, at least they ...
Maccarrone Heredia, Alessandro (Data de defensa: 2016-02-08)
The main objective of this thesis is to understand from a microscopic point of view some of the characteristic phenomena of rotating black holes. The inclusion of rotation gives rise to physics that allows a more precise ...
Gómez Estévez, Juan Luis (Data de defensa: 1983-05-01)
El estudio de las disoluciones líquidas y en particular de aquellas que contienen electrolitos es uno de los más acuciantes, tanto desde un punto de vista teórico como para el análisis de los procesos biológicos y ...
García Santiago, Antoni (Data de defensa: 1995-12-18)
El objeto de estudio de esta tesis es la dinámica intragranular de vórtices a bajas temperaturas en distintas muestras pertenecientes esencialmente a las familias de superconductores de alta temperatura crítica (SCAT) con ...
López Domínguez, Víctor (Data de defensa: 2014-06-11)
The interaction between magnetic nanoparticles and high frequencies, such as microwaves or terahertz waves, is one of the most active field of research, with interesting applications in the screening of electromagnetic ...
Fernández, Daniel (Fernández Moreno) (Data de defensa: 2013-06-14)
The purpose of this thesis is to put forth and present a series of new applications of the gauge/string duality to areas of high energy physics and condensed matter physics. The contributions showcased in this thesis amount ...
Pagonabarraga Mora, Ignacio (Data de defensa: 1995-06-23)
In this thesis we have studied the influence of transport mechanisms on the adsorption kinetics of colloidal suspensions, as well as in the distribution of colloidal particles at the adsorbed layer. Adsorption of colloidal ...
Gil Marín, Héctor (Data de defensa: 2012-05-03)
The goal of this thesis is to study the large scale structure of the Universe from a theoretical point of view. In particular, the different chapters of this thesis focus on developing statistic tools to improve the ...
Sagarra Pascual, Oleguer Josep (Data de defensa: 2016-07-22)
Complex networks grow subject to structural constraints which affect their measurable properties. Assessing the effect that such constraints impose on their observables is thus a crucial aspect to be taken into account in ...
Zarzuela Fernández, Ricardo (Data de defensa: 2014-11-27)
The aim of this thesis was to study quantum phenomena and excitation modes in type-I superconductors and magnetic vortices. The intermediate state in type-I superconductors is characterized by the gradual penetration ...
Miralles Esteban, David (Data de defensa: 2002-01-24)
En la presente tesis se han tratado los siguientes aspectos: 1,- Se ha reformulado la presentación de la teoría de espinores consiguiendo una única definición de espinor que da énfasis al observador y matiza el papel ...
Arteaga Barriel, Daniel (Data de defensa: 2007-06-28)
The basic aim of the thesis is the study of the propagation of particles and quasiparticles in non-trivial backgrounds from the quantum field theory point of view. By "non-trivial background" we mean either a non-vacuum ...
Garolera Huguet, Blai (Data de defensa: 2015-02-27)
The holographic duality between gauge theories and string theories has opened a new door to access the strongly coupled regime of quantum field theories and offers, at the same time, a completely new way to ...
García del Muro y Solans, Montserrat (Data de defensa: 1997-02-18)
Esta memoria presenta el estudio de las propiedades magnéticas de dos sistemas físicos pertenecientes a lo que puede considerarse una nueva generación de materiales, los constituidos por entidades básicas de tamaño ...
Orellana, Laura (Data de defensa: 2014-05-30)
Protein structure, dynamics and function, are inseparable in order to understand the mechanisms of Life at the molecular level. From the structure comes dynamics, and from dynamics many, if not all, protein functions. ...
