Quantum entanglement and quantum state estimation = Entrelazado cuántico y estimación de estados cuánticos
[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 ...
On Friedmann-Lemaître-Robertson-Walker cosmologies in non-standard gravity
[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 ...
Instabilities in Newtonian and non-Newtonian fluids
[spa] Durante la tesis se realizó un estudio experimental de inestabilidades hidrodinámicas en dos sistemas muy diferentes. Estudiamos inestabilidades laterales en dedos de Saffaman-Taylor sujetos a dos tipos de ...
Interplay between anisotropy and disorder in ferroelastics: structures and thermodynamics
[spa] Esta tesis se enmarca dentro del estudio de los efectos de inhomogeneidades en materiales funcionales, dentro de los cuales podemos citar a los materiales que presentan magnetoresistencia colosal, superconductores ...
From molecular force generation to large scale cellular movements
[eng] The propulsion mechanisms that drive the movements of living cells constitute perhaps the most impressive engineering works of nature. Still, it is simply the interaction between molecules which is responsible for ...
Physico-chemical aspects on molecular motors
[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, ...
Experiments on perturbed Saffman-Taylor flows
We have performed pattern formation experiments where a relatively well understood system (flow in a Hele-Shaw cell) is perturbed either by means of a lattice of grooves or by the use of viscoelastic fluids. We have extended ...
Roughness experiments of viscous fluid interfaces in disordered Hele-Shaw cells
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 ...
New Physics in the Electroweak Sector Under Scrutiny at LHC
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, ...
Nucleation and cavitation in liquid helium
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 ...
Time Dependent Processes in Magnetic Systems
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 ...
Entanglement, quantum phase transitions and quantum algorithms
From the seminal ideas of Feynman and until now, quantum information and computation has been a rapidly evolving field. While at the beginning, physicists looked at quantum mechanics as a theoretical framework to describe ...
Front Microrheology of biological Fluids
Since Poiseuille times, several techniques has been developed to measure the viscosity of blood. During the 60's and 70's, with the appearance of the first rheomethers, the rheological properties of blood were accurately ...
Electronics control and signal processing for the LHCb fast calorimeter detectors
LHCb is one of the four large experiments of the Large Hadron Collider (LHC) based at CERN. The LHCb experiment is taking data at its nominal design luminosity. However, in order to distinguish among models of new physics, ...
Functional organization and networ resilience in self-organizing clustered neuronal cultures
Major dynamical traits of a neuronal network are shaped by its underlying circuitry. In several neurological disorders, the deterioration of brain's functionality and cognition has been ascribed to changes in the topological ...
Brassinosteroids role in arabidopsis root development : theoretical and experimental approaches
This PhD thesis represents an advance in the present understanding of the spatiotemporal control of model plant Arabidopsis thaliana root growth and development. The size and structure of a living organism are tightly ...
Dynamics of cellular decision making processes
Cells, either as unicellular organisms or as part of a tissue of a multicellular organism, can acquire different functions thanks to their capability of changing their expression state. The enzyme synthesis, cell division ...
Self-organization and cooperativity of cytoskeletal molecular motors
The present work deals with different aspects concerning the collective action of cytoskeletal molecular motors. The thesis is organized in two parts: the first part corresponds to the study of the cooperative action of ...
Fluctuations, gene circuit architecture and stem cell quiescence
Biological development is a complex process in which, from a single cell, a whole multicellular organism arises. The formation of this intrincate structures requires a very precise regulation in space and time. This ...
Some theoretical and experimental aspects of axion physics
In this thesis we study axions, a byproduct of the Peccei-Quinn solution to the strong CP problem, which are also a viable candidate for the dark matter content of the Universe. In the first part of the thesis, we ...
