BIOGRAPHIE

Je travaille en physique théorique de la matière condensée. Mes activités de recherche sont centrées autour des systèmes dits à fortes corrélations électroniques. Je m’intéresse tout particulièrement au développement de méthodes permettant de décrire de tels systèmes à partir des premiers principes.

  • Sujets de recherche Correlated quantum materials; electronic structure theory; many-body quantum physics

  • Thèmes de recherche Matière quantique et topologique
  • Mots-clés Electronic correlations in quantum materials, Dynamical Mean Field Theory techniques
