Spontaneous generation of geometry and its possible consequences

Puigdomènech Bourgon, Daniel (Date of defense: 2012-11-06)

In this thesis a viable theory of gravity resulting from the spontaneous symmetry breaking of some more fundamental theory is developed. This fundamental theory does not include any notion of a metric or geometry. All the ...

Stochastic Effects in Quorum Sensing

Weber, Marc (Date of defense: 2014-06-06)

Stochastic fluctuations, or noise, are ubiquitous in biological systems and play an important role in many cellular processes. Experimental evidences have shown that noise affects the reliability of cell coordination in ...

Structure and dynamics of liquid helium systems and their interaction with atomic dopants and free electrons

Mateo Valderrama, David (Date of defense: 2013-05-02)

This thesis presents a collection of four papers published in peer-reviewed scientific journals plus a manuscript yet to be submitted, all of them in the field of low temperature physics and quantum fluids. Each of these ...

The properties of antikaons in hot and dense matter

Tolós Rigueiro, Laura (Date of defense: 2003-05-09)

Understanding the behavior of matter under extreme conditions of density and temperature, such as those found in neutron stars or in heavy-ion collisions, requires a good knowledge on the modification of the properties of ...

Theories of modified gravity and reconstruction schemes of cosmological models

López Revelles, Antonio Jesús (Date of defense: 2013-11-08)

En esta memoria de tesis se expone el trabajo llevado a cabo por el doctorando durante los últimos cuatro años, el cual versa principalmente sobre diversos aspectos de soluciones cosmológicas obtenidas a partir de teorías ...

Thermodynamical Properties of Nuclear Matter from a newline Self-Consistent Green's Function Approach

Rios Huguet, Arnau (Date of defense: 2007-02-23)

The main contribution of this thesis concerns the application of the Luttinger-Ward formalism to the study of the thermodynamical properties of nuclear matter. This formalism is devoted to compute the different thermodynamical ...

Time Dependent Processes in Magnetic Systems

Iglesias, Oscar (Date of defense: 2002-05-24)

En este trabajo se presentan modelos para el estudio de los procesos de dependencia en el tiempo de las propiedades magnéticas de diferentes tipos de materiales magnéticos, básicamente sistemas de partículas pequeñas y ...

Topics in quantum Nanostructure Physics: Spin-Orbit effects and Far-Infrared Response

Malet Giralt, Francesc (Date of defense: 2008-05-13)

We have investigated several properties of semiconductor electronic nanostructures. In the first part of the thesis, within the density functional theory we have addressed the ground state and the dipolar response of quantum ...

Turbulent bubble suspensions and crystal growth in microgravity. Drop tower experiments and numerical simulations

Bitlloch Puigvert, Pau (Date of defense: 2012-10-11)

We study the formation and spreading of a turbulent jet of bubbles in microgravity. This has been analyzed from the recordings obtained in previous experimental campaigns of microgravity. Results have been compared with a ...
