Job announcements relevant to people interested in electronic structure calculations…
Due to the large number of posts recently, there is currently a delay of several weeks between posts being submitted and the corresponding emails being distributed to all users. Please bear with us while we try to improve this. In the meantime – and until this notice is removed – it would assist us considerably if you could submit only important and/or urgent posts and thus help to reduce the size of the mail queue. Under no circumstances should you resend posts multiple times when you find the emails are not distributed immediately.
In light of the Russian military offensive in Ukraine, we request that announcements relating to events, jobs and other activities associated with institutions supported by the Russian and Belarusian states are not posted to the Psi-k forum.

Magnetic skyrmions, topologically protected chiral spin structures with particle-like properties, have attracted tremendous attention due to their potential application in next-generation spintronics devices such as racetrack memories, logic gates, and qubits for quantum computing. The recent discovery of 2D magnetic materials opened new opportunities for topological spin structures in atomically thin van der Waals (vdW) materials. Stabilizing skyrmions in 2D magnets have several potential advantages. These include avoiding pinning by defects, the possibility of forming skyrmions with a minimum thickness, and easy control of magnetism via external stimuli. The study of magnetic skyrmions in 2D magnets is still in its early stage.
The purpose of this Master’s thesis is to explore magnetic skyrmions (e.g., generation, stability, detection, etc) in atomically thin vdW materials by density functional theory (DFT) combined with the atomistic spin model.
This internship requires a taste for modeling. We will use electronic structure codes based on DFT. Moreover, we will also apply and extend the existing standard spin model (Heisenberg exchange, Dzyaloshinskii-Moriya interaction, magnetocrystalline anisotropy, Zeeman energy, etc). The results obtained will be analyzed with the possibility of publication in international scientific journals. Funding for a Ph.D. starting in October 2023 is already secured (ANR support).
Your profile
- Master in physics (e.g., Fundamental physics, condensed matter physics), nanosciences, materials science, or any other equivalent majors.
- Good background in quantum mechanics, solid-state physics, and condensed matter theory.
- Programming skills (Fortran, Python, or Bash) are not mandatory but will be considered an advantage.
What do we offer?
- Funding for a Ph.D. thesis starting on October 2023
- Supervision by Dongzhe Li (CNRS permanent researcher)
- Collaborations: R. Arras and L. Calmels (local, CEMES/CNRS), S. Haldar and S. Heinze (international, University of Kiel, Germany)
- Working in an innovative and exciting CEMES/CNRS institute (>60 permanent researchers)
- You will learn/improve your theoretical/computational skills and will prepare yourself for your future career.
