Melé Messeguer, Marina (Date of defense: 2013-07-12)
In this thesis we study and characterize the behavior of Bose-Einstein condensates in a BJJ, using two different theoretical formalisms: the mean-field approximation (with the Gross-Pitaevskii equation) and many-body ...
González Alonso, David (Date of defense: 2014-04-25)
Bé sigui el canvi de temperatura que experimenta un material a l’aplicar-li un camp magnètic en condicions adiabàtiques, o bé sigui el canvi d’entropia del material com a conseqüència de la modificació del camp magnètic en ...
Mur Petit, Jordi (Date of defense: 2006-01-11)
En aquesta tesi presentem un conjunt d'estudis sobre sistemes atòmics on els efectes quàntics són especialment destacats. Aquests estudis s'han dut a terme aplicant diverses tècniques de la física teòrica de molts ...
Blanch Mercader, Carles (Date of defense: 2015-03-04)
The thesis belongs to the field of biophysicis, in particular we evaluate from a physicial perspective biological processes that occur at the celular and multicelular scales involving collective phenomena of self-organization. ...
Pérez Carrasco, Rubén (Date of defense: 2013-02-04)
Cells are the minimum unit of life. They are born, they eat, the may grow, they may move, and, eventually, they die. By contrast, from a physicist point of view, cells are systems out of equilibrium continuously transducing ...
Illa i Tortós, Xavier (Date of defense: 2007-01-23)
S:<br/><br/>L'objectiu principal d'aquesta tesi és aprofundir en l'estudi dels models microscòpics que permeten estudiar la histèresi. Aquest fenomen està present en moltes àrees de la física i ha despertat l'interès de ...
Rosa Agostinho, Nuno Filipe (Date of defense: 2019-10-17)
For more than half a century, colliders have been in the forefront of studying the Standard Model (SM) predictions. The pinnacle of both SM and colliders occurred when on July the 4th 2012, at CERN Large Hadron Collider, ...
Gómez Orlandi, Javier (Date of defense: 2015-09-09)
In this thesis we apply a multidisciplinary approach, based on statistical physics and complex systems, to the study of neuronal dynamics. We focus on understanding, using theoretical and computational tools, how collective ...
Pérez-Obiol Castañeda, Axel (Date of defense: 2014-02-11)
In this thesis we have described the weak Lambda N to NN interaction, which is the main responsible for the decay of heavy hypernuclei, within the effective field theory (EFT) framework. The EFT is developed up to second ...
Parreño Garcia, Assumpta (Date of defense: 1997-05-22)
In single A hypernuclei, a A hyperon can occupy any orbital in the hypernucleus since it is free from the Pauli exclusion principle due to its additional quantum number strangeness. <br/><br/>Due to the Pauli blocking ...
Guilleumas, Montserrat (Date of defense: 1995-07-20)
Las transiciones de fase no siempre ocurren bajo condiciones de equilibrio. Un fluido puede ser conducido a un estado metastable. A pesar de ser internamente estable, existe otra configuración con un potencial termodinámico ...
Sáez Gómez, Diego (Date of defense: 2011-03-31)
[spa] El proyecto de tesis está enfocado en el estudio de la evolución del Universo y más concretamente en la explicación del mecanismo que produce su actual expansión acelerada, y que probablemente sea el mismo que ha ...
González Fraile, Juan (Date of defense: 2014-09-05)
In this thesis we present several studies on the origin of masses at the LHC. First we study the indirect effects of new physics on the couplings of the recently discovered Higgs boson and on the electroweak symmetry ...
Casanellas Vilageliu, Laura (Date of defense: 2013-03-22)
Wormlike micelles are viscoelastic fluids that present an intermediate behavior between solids and ordinary liquids since they are elastic at short time scales but flow easily at large time scales. In opposition to Newtonian ...
Cerutti, Francesco (Date of defense: 2013-07-16)
The main problematics related to the determination of a set of Parton Distribution Functions (PDFs) are presented and, after a brief discussion on different strategies adopted by other groups to address them, the NNPDF ...
Formosa Jordan, Pau (Date of defense: 2013-04-29)
Multicellular organisms are constituted by different kinds of cells which are arranged in a particular way, forming tissues with specific functions. The organization of these different cells can give rise to regular ...
Ciudad Álvarez, Aleix (Date of defense: 2008-05-15)
[eng] The discovery of molecular motors was not a single and isolated event but a set of gradual approaches from microscopic to nanoscopic systems. For example, the knowledge of the activity of muscle cells is pretty old, ...
Acín dal Maschio, Antonio (Date of defense: 2001-06-01)
[spa] En esta Tesis se ha realizado en el marco de la Información Cuántica, una nueva disciplina de la Física Teórica en la que se funden la Mecánica Cuántica con la Teoría de la Información. El estudio se ha centrado en ...
Rodríguez Lázaro, Guillermo (Date of defense: 2014-06-30)
The mechanics and elasticity of red blood cells (RBCs) determine the capability to deform of these cells when passing through the thinnest capillaries, where the delivery of oxygen takes place. The understanding of the ...
Soriano i Fradera, Jordi (Date of defense: 2003-02-28)
Se presenta un trabajo experimental sobre el crecimiento de interficies rugosas en medios desordenados. El experimento consiste en una celda de Hele-Shaw en cuya placa inferior se han distribuido una serie de obstáculos ...
