Prignano, Luce (Fecha de defensa: 2012-07-20)
During the last decades, it has become clear that systems formed by many interacting parts show emergent dynamical properties which are inherently related to the topology of the underlying pattern of ...
Fariña Sierra, Noela (Fecha de defensa: 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 ...
Fernández, Daniel (Fernández Moreno) (Fecha 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 ...
Miguel López, María del Carmen (Fecha de defensa: 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 ...
Alarcón Oseguera, Francisco (Fecha de defensa: 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 ...
Valentí i Vall, M. Roser (Fecha de defensa: 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 ...
Cuadra-Solís, Pedro-de-Jesús (Fecha de defensa: 2015-10-29)
In this thesis we have studied the vortex dynamics in type-2 superconducting thin films made of La1.82Sr0.18CuO4, patterned Pb and MgB2, by means of the combination of microwave, dc and ac measurements. ...
Camuñas i Soler, Joan (Fecha de defensa: 2015-03-02)
Single-molecule techniques allow to following biomolecular reactions with unprecedented resolution. Particularly, optical tweezers can be used to manipulate and apply forces to individual molecules ...
Lendínez Escudero, Sergi (Fecha 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 ...
Miralles Esteban, David (Fecha 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 ...
