Computational study of MOFs for an efficient carbon capture Applications are invited for a fully funded 3-years PhD position to work on the electronic structure modeling of porous coordination polymers starting on October 1st 2017 and funded by the ANR ComputationalCarbonCapture. We propose to design novel families of MOFs whose high affinity for CO2 can… Read More
New paper on excitations in hexagonal Boron-Nitride. Core and low energy electronic excitations have been studied in hexagonal boron nitride by means of angular resolved electron energy loss spectroscopy and theoretical calculations.

In this work we studied the C-C defect complex in silicon. We used different approaches in such a way to identity the defect configuration responsible for the strong light emission in irradiated silicon. Our clues point towards a particular configuration, even if we suspect that in a damaged sample different type of complexes could be… Read More
In this work we compare the optical absorption of extended systems calculated starting from the density-density and current-current linear response formalisms within the equilibrium many-body perturbation theory(MBPT). We show how, using the latter, one can incur in errors due to quasiparticle lifetimes, electron-hole interaction or the presence of a Drude tail. These errors are found… Read More
Recently I joined the SciPost journal as editor fellow. It is the first time that I work as editor for a journal. At the beginning I thought that this role would have taken me much time but then I realized that the editor work often takes less time than that of the referees. Probably in… Read More
At present I’m working in the TSN group “Théorie et Simulation Numérique” (Theory and numerical Simulations) at CINaM. If you want to know what people do in this group, have a look to this short presentation on our research activity. Contact us for possibility of master, PhD or post-doc positions.
My new talk on Many-Body Perturbation Theory (MBPT) in chemistry is online. If you want to know what MBPT can do in finite systems have a look to this talk. There is an historical introduction and then I discuss different approximations as GW, BSE and present applications in organic chemistry. More recent progresses are presented… Read More
The first draft of my thesis for the accreditation to direct research (Habilitation à Diriger des Recherches) is available online. The thesis covers my studies of the non-linear response in solids and nanostructures by means of real-time simulations. In the thesis I discuss how to couple electrons and external fields by means of Modern Theory… Read More
A new poster on our work on real-time density polarization functional theory. In presence of a time-dependent macroscopic electric field the electron dynamics of dielectrics cannot be described by the time-dependent density only. We present a real-time formalism that has the density and the macroscopic polarization P as key quantities. We show that a simple… Read More
A 18 month post-doctoral position is available, from September 1st 2016, at the “Laboratoire d’Etude des Microstructures” (http:// http://lem.onera.fr/) in strong collaboration with the “Centre Interdisciplinaire de Nanoscience de Marseille” (http://www.cinam.univ-mrs.fr/), as part of the European Union Graphene Flagship project (http://graphene-flagship.eu/). Since graphene takeoff in the 2000’s, the field of two-dimensional systems has been gradually… Read More
