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. Paper: Angular resolved electron energy loss spectroscopy in hexagonal boron nitride Poster: Modeling excitons in bulk and single-layer hBN
My code to calculate non-linear response in solids and nanostructure is finally online. The first tutorials are available, and soon I will finish the other ones. Full free to use it and let me know if you find bugs or strange things.
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
Performing RPA calculations with yambo in large systems can be a problem due to the memory requirement. In fact the code does not distribute the dielectric constant at the different frequencies among the processors. The solution is to run different calculations for each frequency of the dielectric constant and then joind the outputs. Here my… 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
