peer reviewed / AbstractTopological defects are ubiquitous, they manifest in a wide variety of systems such as liquid crystals, magnets or superconductors. The recent quest for non‐abelian anyons in condensed matter physics stimulates the interest for topological defects since they can be hosted in vortices in quantum magnets or topological superco...
peer reviewed / The nanoscopic magnetic texture forming in a monolayer of iron on the (111) surface of iridium, Fe/Ir(111), is spatially modulated and uniaxially incommensurate with respect to the crystallographic periodicities. As a consequence, a low-energy magnetic excitation is expected that corresponds to the sliding of the texture along the i...
This thesis explores the physics of point defects, conducting a comprehensive investigation through both theoretical and experimental approaches. In a first part, we emphasis the rich behaviour of defects, leading to their detailed classification. Non-radiative defect-mediated recombinations are described based on the Shockley-Read-Hall (SRH) stati...

Compared to other types of granular materials, cohesive granular materials (e.g. cornstarch, lactose powder) display specific flowing properties that cause problems in many applications. Investigating the flow of cohesive granular materials is complex because the triboelectric effect, that might be responsible for cohesion in granular materials, is...
peer reviewed / Transformation optics applied to low frequency magnetic systems have been recently implemented to design magnetic field concentrators and cloaks with superior performance. Although this achievement has been amply demonstrated theoretically and experimentally in bulk 3D macrostructures, the performance of these devices at low dimensi...
editorial reviewed / In the last two decades, Phase Change Materials have emerged as active components of non-volatile memories thanks to their ability to switch extremely rapidly from a conducting crystal to a semiconducting glass. Ab Initio simulations helped understanding the structure and some properties of the glassy phase, like aging, but als...
peer reviewed / In this communication, we demonstrate numerically and experimentally the remarkable DC magnetic screening ability of hybrid superconducting screens combining a 30 mm-diameter disk-shaped superconducting bulk with different closed superconducting loops made from coated conductors. The loops are placed coaxially with the bulk. The DC ...
peer reviewed / Hypothesis Metallic nanowires, particularly polyol-grown silver nanowires, exhibit a morphological instability at temperatures significantly lower than their bulk melting point. This instability is commonly named after Rayleigh's description of the morphological instability of liquid jets, even though it has been shown that its quan...
