Laboratory for Matter in extreme condition (UPS) has an opening for a Postdoctoral position  to implement the relaxed core in the ABINIT software. You will join the group at CEA in Arpajon.

The study of Warm Dense Matter (WDM) is a challenging field that is at the crossroads
between condensed matter and plasma physics. XANES (X-ray Absorption Near Edge
Structure) was recently extended to WDM regime and is now a key diagnostic to follow the complex mechanism of phase transition.

XANES absorption computed using Density Functional Theory combined within the framework of Projected Augmented-Wave and linear response theory makes use of frozen core approximation. This severely limit the description for extreme pressure condition (~100GPa and above). The challenge is now to go beyond the frozen core approximation.

During this post-doc, you will improve the description of XANES spectra for extreme conditions in extreme pressure (T>10000K) and temperature (P>100GPa) by implementing the relaxed core technique. You will have to run DFT based molecular dynamics simulations on massively parallel computers. All this work will be done with a close interaction with experimental teams.

You must have a strong expertise in solid states physics and an experience in ab initio molecular dynamics simulation. A good knowledge on programming is also necessary (Fortran, MPI, Linux, Python)
