Orbital Magnetism in Topological Insulators

Laboratoire de Physique des Solides; Centre de Physique Théorique

I am currently investigating the orbital magnetism of topological insulators, focusing on the emergence of orbital magnetic moments and their interplay with topology. This research aims to develop a deeper understanding of how orbital magnetization behaves in both bulk and edge states, particularly in systems where conventional spin magnetism is weak or absent. By exploring theoretical models and numerical simulations, I seek to uncover new mechanisms that could lead to novel magnetic phases and potential applications in spintronics.

Topology of 2D Semimetals on Graphene

Centre de Physique Théorique

In this project, I investigated the topological properties of two-dimensional semimetals based on graphene, focusing on their electronic structure and emergent quantum phases. By analyzing band topology and symmetry-protected features, I explored how these systems can host exotic electronic states.

Out-of-Equilibrium Transport in Classical Hall Devices

Laboratoire des Solides Irradiés; Centre de Physique Théorique

In this project, I studied out-of-equilibrium transport in a classical Hall device, focusing on the influence of symmetric versus antisymmetric transport matrices on the Hall voltage. By attaching a lateral circuit to the Hall device, we explored how different transport symmetries impact voltage distributions and current flow. This work aimed to provide insights into the role of transport properties in shaping Hall responses beyond equilibrium conditions.

Coupling Between Jupiter's Magnetosphere, Ionosphere, and Thermosphere

Institut de Recherche en Astrophysique et Planétologie

This project focused on the complex interactions between Jupiter's magnetosphere, ionosphere, and thermosphere, which govern the coupling between the plasma distribution in the planet's magnetodisk and the ultraviolet auroras observed at its poles. By studying these interactions, we aimed to better understand how large-scale magnetospheric dynamics drive auroral emissions and energy transfer processes in Jupiter's upper atmosphere.
