Antoine MARIE

Hello!

I'm a postdoctoral researcher in Dominika Zgid's group at the University of Warsaw. I am a theoretical chemist with a keen interest for electronic structure theory. In particular, I really like investigating the connection with adjacent fields such as nuclear physics, condensed matter or materials science. Currently, I'm working on the description of magnetic compounds with strong spin-orbit coupling using a relativistic \(GW\) framework.

I did my PhD in Pierre-François Loos' group at the Laboratoire de Chimie et Physique Quantiques in Toulouse. My research was focusing on the development of Green's function-based methods for quantum chemistry (see, for example, Ref. 7 and 13). In particular, I was very interested in post-\(GW\) self-energies, so-called vertex corrections (see Ref. 14). In the mean time I was also extending the QUEST database of excitation energies to ionization potentials (see Ref. 10).

Before my PhD I obtained a Master degree in "Computational physics and chemistry" at the Ecole Normale Supérieure de Lyon. During this period, I had the opportunity to do two internships, both in the same group as my current one, during which I worked on analytic extension of perturbation theory in the complex plane in quantum chemistry (see Ref. 1) and on state-specific variational coupled-cluster excited-state solutions (see Ref. 3).

Finally, prior to my PhD, to fulfill the requirement of the ENS' diploma, I spent one year abroad as a research intern. During this time, I spent five months at the Physical and Theorical Chemistry Laboratory in Oxford. There, I worked under the supervision of Hugh Burton on the multiple stationary points of the CASSCF energy landscape. Then, I moved to Amsterdam to learn, within Paola Gori-Giorgi's group, the Strictly Correlated Electrons formalism of Density Functional Theory. We used this method to investigate a one-dimensional model of many-body localization.
