Modeling spin transport in heterostructures in the presence of spin-orbit coupling (SOC) presents different challenges on both conceptual and technical aspects. To date, most theoretical predictions have been achieved using model-like systems neglecting the orbital character of the conduction electrons, involving only a handful of bands and assuming a simplified version of SOC effects.
The project aims to develop an effective and predictive modeling platform around ab initio quantum transport, enabling simulations of realistic spintronic and spin-orbitronics devices. For that, we will develop new functionalities in the previously developed electron transport code based on nonequilibrium Green's function (NEGF) formalism.
- We will implement new tools for quantifying and predicting spin-orbitronics properties in nanostructures.
- We will develop a large-scale ab initio quantum transport platform for spin-orbit transport properties in 2D van der Waals interfaces and tunnel junctions containing topological spin structures such as skyrmions, anti-skyrmions, or bimerons.
- Applicants should hold a Ph.D. degree in Physics, Materials Science, Nanosciences, or a closely related discipline, with a strong background in DFT and solid-state physics.
- Good programming skills (Fortran or Python) are mandatory.
- Experience in code development, quantum transport calculations based on NEGF, or SOC-related physics is considered an advantage.
Contexte de travail
CEMES is a CNRS laboratory which brings together nearly 65 researchers or teacher-researchers, nearly 50 doctoral or post-doctoral students and more than 30 engineers or technicians. The recruited person will do their thesis in the MEM group (Materials and devices for Electronics and Magnetism) at CEMES. This group studies the physical properties of (nano)materials constituting the building blocks of conventional electronics and spin electronics, as well as the link between atomic structure and electronic, optical and magnetic properties of these (nano)materials. The ab initio calculations carried out as part of this thesis will be carried out at the CALMIP calculation center (calculations in Midi-Pyrénées) as well as at national calculation centers. This position is funded as part of the ANR MATRICES project. You will learn/improve your theoretical/computer skills and prepare for your future career as a researcher. The position is located in a sector falling under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with regulations, that your arrival be authorized by the competent authority of the MESR
