Bertrand Dupé, USIAS Fellow 2019

Bertrand Dupé obtained his PhD, with a thesis on dielectric and magnetic properties of multiferroic thin films, at the École Centrale Paris (now CentraleSupélec) in 2010. After a year of postdoctoral research at the French Alternative Energies and Atomic Energy Commission (CEA), he decided to focus on the theoretical studies of magnetic nanomaterials based on density functional theory at the University of Kiel (Germany) and at the Jülich Research Centre (FZG), Germany. He participated in the European project Magnetic Skyrmions for nanospintronic devices: a Future Emerging Technology (MAGicSKY-FET), in collaboration with Professor Albert Fert’s group in Paris on the link between topology and magnetism.

In 2016, he was recruited as Interim Professor at the Johannes Gutenberg University Mainz (Germany) and then as a full researcher in 2017. Currently, he is leading the INSPIRE research group of five people focusing on the link between topology and electronic structure.

Project - Coupled spin and charge femto-second dynamics for topological material

Modern societies are based on fast and reliable communication media that are also energy efficient. At the atomic level, information is transmitted by a fundamental constituent of matter called the electron. Similar to rivers, electrons flow in matter and their accumulation or depletion is associated with the presence of a data bit of 1 or 0, respectively.

In this project, we intend to establish a new methodological framework where information is transmitted without moving matter. The information vector will be constituted of the spin rather than the charge of the electron, which will considerably accelerate the speed of information. We foresee that light and spins could act as the information medium. To study their interactions, we will develop numerical tools that are parametrised by density functional theory, where the dynamics of light and the electron charge and spin will be treated on an equal basis. We will thus explore the dynamics of topologically protected magnetic textures such as skyrmions and hopfions.

Bertrand Dupé will be welcomed by Professor Paul-Antoine Hervieux, Institute of Physics and Chemistry of Materials of Strasbourg (IPCMS), during the project.
