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
We are organizing the first “Marseille Condensed Matter Workshop” on Optical and Magnetic properties of complex materials from the 12th to the 14th September at CINaM (Marseille). The aim of the workshop is to bring together researchers working on different research communities to promote exchange and share research experiences. More info can be found there:… Read More
We present a new paper on Density Functional Polarization Theory (DFPT). This theory is an extension of Time-Dependent-DFT where the exchange correlation functional depends not only from the density but also from the polarization P. Thanks to this explicit dependence on P it is possible solve different problems of TD-DFT in periodic systems with a… Read More
The GDR-REST (Research group on Theoretical Spectroscopy) is organizing its first general meeting from the 23rd to the 27th of May 2016, here the website for all details. The GDR-REST meeting aims to bring together different communities of theoretical spectroscopy which are/were historically separated, but unified under a very precise and important subject: the excited-states… Read More
Since October 2015 I’m in charge of the Theory Seminars at CINAM. If you are in Marseille and you are interested in Condensed Matter Physics, have a look to our seminar page. We organize a new seminar every two weeks, with internal or invited speakers. If you would like to present your research in our… Read More
ANR (Agence Nationale de la Recherche) is the National French Agency for Research. It is an independent agency created in 2005 that funds scientific teams, both public and private, in the form of short-term research contracts. In general the idea to fund research on projects is not bad but at present ANR is not working … Read More
Here my new poster that I will present to the PSI-K conference on the GW renormalization of the electron-phonon interaction. In this poster I summarize results from different group that used GW approximation to correct the electron-phonon coupling obtained from the Kohn-Sham Hamiltonian. Thanks to these corrections it was possible to reproduce and predict different… Read More
I just attended a seminar on network theory. The speaker[1] presented some interesting results on the reconstruction of communities in static or temporal networks. The talk was clear and the results well presented, but the thing that impressed me more were the references. The results, he had shown, were produced from 2012 to 2015 and… Read More
