[eng] This doctoral thesis deals with the study of the collective behavior of active particles using computacional simulations of semi-dilute solutions of microswimmers. Results are obtained for the polar order parameter, ...
In this thesis we asses the phenomena of arising interactions in soft matter in coexistence with soft active matter. As a non-equilibrium bath we introduce ensembles of self-propelled particles, granular shaken beds, and ...
[eng] This thesis develops, validates, and explores applications of the Franzese-Stanley (FS) coarse-grained model for bulk water, ultimately intended to represent the solvent in large-scale simulations of biological ...
In the present thesis, single-molecule experiments have been carried out using optical tweezers with a temperature controller. Employing equilibrium and non-equilibrium experiments, the free energy, enthalpy, and entropy ...
El trabajo de esta tesis ha consistido en estudiar, preparar y caracterizar los compuestos pertenecientes a la familia M'M"BX-sub4, concretamente los de fórmula LiMSO-sub4, en donde M = Na+, K+ y NH-sub4+, para posteriormente ...
[eng] Geometrical frustration is a general phenomenon influencing the behavior of diverse natural systems across different length scales. Geometrical frustration arises when the symmetry of the interaction among building ...
Most systems in Nature manifest complex transport phenomena arising from the interplay of multiple time and length scales, be them intrinsic in the system’s dynamics or externally enforced. It is the case, for instance, ...
[eng] This thesis will present a body of articles on the research topic of soft matter. Soft matter is a research subfield of condensed matter, where the energy required for deforming the media is comparable to that of ...
This thesis was part of the European consortium MESOBRAIN, a team of 5 organizations that joined efforts in nanofabrication, cell culturing, imaging and data analysis to build tailored human 3D networks. The thesis timing ...
THESIS SUMMARY<br/><br/>TEXT:<br/><br/>This thesis is made of two parts. In the first one, the issue of entanglement in many body systems is addressed. The concept of entanglement and some of the recent progress on the ...
In this thesis, we have studied mechanical aspects of some biological processes in cells and tissues, which we addressed by developing theoretical models based on the physics of soft active matter. The thesis contains three ...
Most of the real-world complex systems are best described as complex networks and can be mathematically described as oscillatory systems, coupled with the neighbours through the connections of the network. The flashing of ...
Complex networks are mathematical representations of the interaction patterns of complex systems. During the last 20 years of Network Science, it has been recognized that networks from utterly different domains exhibit ...
The urgent need to reduce our footprint on the earth environment is leading to ever more stringent commitments to decrease greenhouse gases emissions, which entails one of the greatest challenges that mankind has to tackle. ...
Solid state materials are candidates to exhibit a large field-driven thermal response in the vicinity of first-order transitions. The strong sensitivity of the transition temperature with the applied field and the latent ...
Living organisms and systems are continually converting energy, either internally stored or transduced from their surroundings, into motion. This activity and the resulting self-propulsion constantly push these biological ...
The topics dealt with in this thesis are all part of the general problem of social consensus, namely how a convention flourish and decay and what motivates people to conform to it. Examples range from driving on the right ...
The goal of this thesis is studying hydrodynamic effects on active colloidal suspensions. Hydrodynamic interaction is propagated through the fluid in which the colloids displace due to the flow they create during their ...
The subject of this thesis is viscous fingering in Hele-Shaw cells, or Hele-Shaw flows. We look for insights into the fundamental mechanisms<br/>underlying the physics of interface dynamics, which we hope will exhibit some ...
In the present thesis, we propose to explore neuronal circuits at the mesoscale, an approach in which one monitors small populations of few thousand neurons and concentrates in the emergence of collective behavior. In our ...
