Type of internship
Théorique, numérique Description
Understanding the behavior of carbon under extreme pressures and temperatures is
crucial for inertial confinement fusion (ICF) experiments and for interpreting data from
facilities such as the National Ignition Facility (NIF). In these conditions, carbon enters
the warm dense matter (WDM) regime, where its electronic and structural properties
strongly affect energy transport and X-ray diagnostics.
This internship aims to model warm-dense carbon and compute key quantities relevant
for X-ray Thomson scattering (XRTS) analysis at NIF.
The student will:
- Perform DFT-MD simulations of carbon at conditions relevant to ICF experiments.
- Calculate the electrical conductivity from these simulations using the Kubo–
Greenwood formalism.
- Compute the electronic structure factor S(q,ω), which determines the XRTS
signal.
The student will gain hands-on experience with first-principles simulations of matter
under extreme conditions and contribute to the analysis of XRTS data from NIF
experiments. The results will help improve our understanding of transport and structure in
warm-dense carbon, directly supporting ongoing ICF research. The results may form the
basis for a future publication or PhD project.
