Research Topics and Team
DFT and MBPT are two state-of-the-art frameworks for the description and prediction of material properties, such as photoemission, optical absorption and metal-insulator transitions. In particular I am interested in the description of strongly correlated materials, which physics is difficult to capture using standard approximations.
I currently supervise a team of one postdoc, two PhD students, and a master student.
After a one-year postdoc position with me and my colleague Pierre-François LOOS (LCPQ), Stefano is now working with Michel CAFFAREL (LCPQ) and myself on merging QMC with many-body perturbation theory. Stefano is also working on other side projects on strong electron correlation.
Roberto has just started his PhD with my colleague Pierre-François LOOS (LCPQ) and myself. He is exploring new approximations to the kernel of the Bethe-Salpeter equation, which is used in MBPT for the description of optical spectra.
Gabriele has just started his PhD with my colleague Arjan BERGER (LCPQ) and myself. Being the one-body and the two-body Green’s functions too simple for him, he is working with the three-body Green’s function!!!
