Black Holes: New Perspectives from Higher Dimensions

Haddad, Nidal (Date of defense: 2012-10-27)

However successful classical general relativity is, it faces non-normalizability problems at the quantum mechanical level. Nevertheless, it predicts the existence of black holes, which are thermal objects that are expected ...

Carácter asintótico de la invariancia adiabática

Navarro Veguillas, Luis (Date of defense: 1965-01-01)

En el estudio de la Física del Plasma y, más concretamente, en la llamada aproximación del centro guía se trata el problema del movimiento de partículas cargadas en un campo magnético variable. Los resultados obtenidos se ...

Coarse-Grained Modeling of the Assembly and Mechanical Properties of Viruses

Aznar Palenzuela, María (Date of defense: 2013-10-31)

The main goal of this thesis is to study the physical mechanisms implicated in the self-assembly and mechanical properties of non-enveloped viral capsids using coarse-grained models. The thesis has been divided into three ...

Computational study of the emergent behavior of micro-swimmer suspensions

Alarcón Oseguera, Francisco (Date of defense: 2016-02-08)

It is known that active particles induce emerging patterns as a result of their dynamic interactions, giving rise to amazing collective motions, such as swarming or clustering. Here we present a systematic numerical study ...

Correlated Stochastic Dynamics in Financial Markets.

Perelló, Josep, 1974- (Date of defense: 2001-12-20)

Thesis investigates the dynamics of financial markets. Nowadays, this is one of the emergent fields in physics and requires a multidisciplinary approach. The thesis studies the first work made by the financial mathematicians ...

Correspondences in higher-dimensional gravity

Di Dato, Adriana (Date of defense: 2015-11-12)

In this thesis we have made progress on the study of higher dimensional gravity by focusing on the properties of black holes and branes and their dynamics. We have developed two main projects: • provide several maps ...

Cosmologia i Formació d'Estructures / Cosmology and Structures Formation

Manera Miret, Marc (Date of defense: 2007-06-27)

In this thesis we push forward techniques to learn about the large scale structure formation of the universe. The approach is from theory, observations and simulations. From theory we study the growth of four non standard ...

Cosmological Perturbations in Einstein-Aether Theories

Fariña Sierra, Noela (Date of defense: 2011-10-17)

In this thesis we study the Einstein-Aether (E-A) theory from the point of view of its cosmological perturbations. We are interested in the constraints that may be obtained from this analysis and the special features that ...

Cuantización de ondas gravitatorias planas

Montejo Estevez, Manuel (Date of defense: 1999-11-09)

El objetivo de esta tesis es construir un modelo cuántico para las ondas gravitatorias planas, unas soluciones de vacío de las ecuaciones de Einstein que presentan simetrías análogas a las ondas electromagnéticas en un ...

Customizing a low temperature system for microwave transmission measurements. Quantum transport in thin TiN films and nanostructures

Carbonell Cortés, Carla (Date of defense: 2012-06-22)

The work presented in this thesis consists of two distinct parts. The first years of my work focused on the development and improvement of a new equipment built to study magnetic and electrical properties, particularly ...

Dynamic Properties of Magnetic Colloidal Particles and Holes

Miguel López, María del Carmen (Date of defense: 1985-10-06)

Our main goal is to study certain aspects of the dynamics of fluids with magnetic particles in suspension, based on their promising practical applications as new materials as welI as on its fundamental scientific interest. In ...

Estudi d'algunes ferrites hexagonals uniaxials

Isalgué Buxeda, Antoni (Date of defense: 1984-06-04)

S'ha obtingut la comprensió dels fenòmens donant lloc a l'ordenament magnètic i l'anisotropia magnetocristal.lina de ferrites hexagonals uniaxials. S'han realitzat mesures de difracció de raigs X i de neutrons (per afinar ...

Estudi de sistemes de baixa dimensionalitat i correlació electrònica forta pel mètode de la matriu de transferència

Valentí i Vall, M. Roser (Date of defense: 1989-01-01)

Els sistemes de baixa dimensionalitat han sigut i són atractius als física per diverses raons: - A nivell estrictament teòric són els sistemes més senzills d'estudiar, i, de fet, molts models no trivials en tres dimensions ...
