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 ...

Disorder is present in many systems in nature and in many different versions. For instance, the dislocations of a crystal lattice, or the randomness of the interaction between magnetic moments. One of ...
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 ...
Huguet Casades, Josep Maria (Data de defensa: 2011-02-04)
[eng] Molecular biophysics is a scientific discipline that studies biomolecules. This discipline has experienced a revolution thanks to the development of single- molecule techniques. These techniques ...

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 ...
Colomer de Simón, Pol (Data de defensa: 2016-06-09)
The study of a system from a network perspective focuses on the impact that connectivity between the elements has on the function of the system. The observation and measurement of parameters of real-world ...
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 ...
Serrano Moral, Ma. Ángeles (María Ángeles) (Data de defensa: 1999-05-28)
La tesis presenta una cuidadosa descripción del comportamiento dinámico de las antenas esféricas resonantes de ondas gravitatorias cuando son excitadas por radiación gravitatoria, o también por señales ...
Carbonell Cortés, Carla (Data de defensa: 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 ...
Malgaretti, Paolo (Data de defensa: 2013-10-23)
In this thesis we characterize the behavior of molecular motors when the properties of the cytoplasm they displace through are not homogeneous or isotropic. Anisotropies in the cytoplasm can be induced, ...
