Abstract:
Spin 1/2 quantum spin chains represent the prototypical model for coupled two-level systems. Consequently, they offer a fertile playground for both fundamental and technological applications ranging from the theory of thermalization to quantum computation. Recently, it has been shown that interesting phenomena are associated to the boundary conditions imposed on the quantum spin chains via the so-called topological frustration. In this work, we analyze the effects of such frustration on a few-spin system, with a particular focus on the strong even–odd effects induced in the ground-state energy

Abstract:
We study the depinning transition of a driven chain-like system in the presence of frustration and quenched disorder. The analysis is motivated by recent transport experiments on artificial vortex-flow channels in superconducting thin films. We start with a London description of the vortices and then map the problem onto a generalized Frenkel-Kontorova model and its continuous equivalent, the sine-Gordon model. In the absence of disorder, frustration reduces the depinning threshold in the commensurate phase, which nearly vanishes in the incommensurate regime. Depinning of the driven frustrated

L'objectif de ce travail de thèse est de déterminer les lois fondamentales qui décrivent les écoulement de fluides actifs confinés dans des réseaux hydrauliques. Dans la première partie, je détaille les méthodes expérimentales et le système modèle que j'ai instauré. Ensuite, en me focalisant sur les réseaux hydrauliques réguliers de valence impaire, j'établis une analogie directe entre l'hydraulique active et le magnétisme frustré. Je démontre notamment pourquoi les écoulements spontanés des liquides actifs sont généralement dégénérés, caractérisés par des lignes de courant aux géométries auto

Dans cette thèse, l’étude de plusieurs modèles de systèmes magnétiques frustrés a été couverte. Leur racine commune est le modèle de la glace de spin, qui se transforme en modèle de la glace sur réseau kagome (kagome ice) et réseau en damier (square ice) à deux dimensions, et la chaîne d’Ising à une dimension. Ces modèles ont été particulièrement étudiés dans le contexte de transitions de phases avec un ordre magnétique induit par les contraintes du système : en effet, selon la perturbation envisagée, les contraintes topologiques sous-jacentes peuvent provoquer une transition de Kasteleyn dans

Abstract Topological tailoring of materials at a micro-scale can achieve a diverse range of extreme physical and mechanical properties. Modification of material properties through customizing the structural pattern paves an avenue for novel functional product design. In this paper, a non-periodic microstructure design framework is explored for functional parts design with high-strength and functional property gradation. To address the common problem of geometric frustration in non-periodic microstructure design, we employ a smooth transition layer to connect distinct structural patterns and th
