Abstract:

Conjugated polymers are wide bandgap semiconductors which have a series of conjugated π-orbitals that extend along the polymer ‘backbone’. The π-orbital conjugation can be disrupted by twisting of the polymer, affecting their optical properties. These materials are very useful for devices, where they are frequently found in semicrystalline thin films. In thin films, Frenkel excitons diffuse on a nanometer scale. However, measurement of the diffusion length of excitons in conjugated polymer films is currently very difficult. Disordered packing and twisting of polymers plays a significant role,

Abstract:

The present thesis reviews my scientific works on disordered systems from 1995 until today. They can be roughly categorized into three main classes: (1) non-interacting disordered systems, (2) the two-interacting particle problem, and (3) the interplay of disorder and many-particle interaction. A (4)th chapter is concerned with the implementation of the numerical algorithms. The structure of the thesis reflects this division. The reprints have been added at the end of these main divisions according to their context. For the convenience of the reader, I have ordered them in each chapter alphabe

Abstract:

Motivated by the intriguing features of the insulating regime close to an SIT, I carry out a systematic study of magnetoresistance, elucidating a variety of approach that influence it. In Chapter 2 I introduce a model of hard-core bosons on a two dimensional honeycomb lattice in a magnetic field, as motivated by recent experiments on structured films [38, 39]. This aims at explaining several key features observed in the activated magneto-transport in those experiments. Taking into account long range Coulomb interactions among the bosons, I study the crossover from strong to weak localization

Abstract:

Classical partial transport barriers govern both classical and quantum dynamics of generic Hamiltonian systems. Chaotic eigenstates of quantum systems are known to localize on either side of a partial barrier if the flux connecting the two sides is not resolved by means of Heisenberg's uncertainty. Surprisingly, in open systems, in which orbits can escape, chaotic resonance states exhibit such a localization even if the flux across the partial barrier is quantum mechanically resolved. We explain this using the concept of conditionally invariant measures by introducing a new quantum mechanicall

Abstract:

The work presented in this thesis concerns the dynamics in π-conjugated hydrocarbon systems. Due to the molecular bonding structure of these systems there exists a coupling between the electronic system and the phonons of the lattice. If this interaction, which is referred to as the electron-phonon (e-ph) coupling, is sufficiently strong it may cause externally introduced charge carriers to self-localize in a polarization cloud of lattice distortions. These quasi-particles are, if singly charged, termed polarons, the localization length of which, aside from the e-ph coupling strength, also dep

The modern InGaN technology demonstrates high efficiencies only in the blue spectral region and low current operation modes. The growth of InGaN quantum wells (QWs) on nonbasal crystallographic planes (NBP) has potential to deliver high-power blue and green light emitting diodes and lasers. The emission properties of these QWs are largely determined by the localization of carriers in the minima of spatially inhomogeneous band potential, which affects the recombination dynamics, spectral characteristics of the emission, its optical polarization and carrier transport.

The insulin-like growth factor-1 receptor (IGF-1R) and many of its downstream signaling components have long been implicated in tumor progression and resistance to therapy.

Despite their considerable homology, previous work in our lab and others has shown that IRS-1 and IRS-2 play divergent roles in breast cancer cells. Signaling through IRS-1 promotes cell proliferation, whereas signaling through IRS-2 promotes cell motility and invasion, as well as glycol

The objective of this study was to determine whether nBMP2 affects the immune system, since activation of lymphocytes and other immune cells depends on intracellular calcium transport.

Nous présentons dans ce travail la caractérisation, essentiellement en transport, de couches de graphène épitaxiés élaborées par sublimation contrôlée de carbure de silicium (SiC). Des mesures de transport électroniques sont effectuées à basse température (T~1,6 K) et à fort champ magnétique. Dans une première partie, Il est indispensable de se focaliser sur la méthode spécifique (‘graphite cap') utilisée pour la fabrication de tous les échantillons étudiés dans ce travail au CNM, Barcelone. La méthode de ‘graphite cap' permet d'obtenir des couches de graphène en formes de rubans suffisamment

Abstract:

The nucleo-cytoplasmic compartmentalization enables eukaryotic cells to develop sophisticated post-transcriptional regulations of gene expression. However, managing the exchanges of macromolecules between the two compartments also represents a formidable challenge for the cells. Nucleo-cytoplasmic exchanges rely on specialized soluble carriers and take place at nuclear pore complexes that span the nuclear envelope. Active nucleo-cytoplasmic transport of proteins, in particular, is performed mainly by a family of carriers called karyopherins, which includes about twenty members in mammals. Some
