CNRS (National Scientific Research Center) is the largest research center in France. It employes about 11.000 researchers and its domain of activity ranges from physics to sociology, from chemistry to electronics and so on. Every year researchers are recruited by means of a national open competitive exam. The selection is composed of two parts a… Read More
Thanks to Francesco Sottile the video of my presentation at the “Correlation Meeting 2014” is online. In this talk I explain how GW can be used to correct the electron-phonon matrix elements, and improve the agreement with the experiments as Raman, phonons, band gap renormalization, superconductivity, etc…
New poster on second and third harmonic generation in nanostructures. We studied SHG in two-dimensional crystals and THG in one dimensional nano-ribbons and nanotubes.
My new presentation on the “GW renormalization of the electron-phonon coupling” is available online. This is the talk I gave to the “Correlation Meeting 2014” organized by Pina Romaniello. In this presentation I show that GW corrections are important not only for band structure and energy levels but they also renormalise the electron-phonon matrix elements…. Read More
Since I do not use so often BLAS library for matrix-matrix multiplication, when I have to multiply two matrices with some rectangular shape or with additional operation I always get confused. So I decided to write a simple guide to c/z-gemm in fortran. 1) Simplest case two square complex matrices: A(N,N) and B(N,N) and I… Read More
I searched on internet for different solution, then I found one pleasant for my website. First of all I modified the style.css file to define a nice list in HTML. #MyList { margin-bottom: 20px; } the I added the following PHP code in front-page.php: <center><h2><font color=#051A23>RECENT POSTS … </font></h2> <br> <ul id=”MyList”> <?php query_posts(‘showposts=3’);… Read More

19th ETSF Workshop on Electronic Excitations: Complex systems in Biology and Nanoscience I’m one of the organizer of the workshop “19th ETSF Workshop on Electronic Excitations: Complex systems in Biology and Nanoscience” that will be held in Zaragoza (Spain) from Septembre 23th to Septembre 26th.
I’m one of the organizer of the workshop “Gutzwiller wave functions and related methods” that will be held in Valance (France) from June 16th to June 19th. Here the French announcement, and conference web-page.
We just published a new review on GW and Bethe-Salpeter (BSE) for molecules. In the review we discuss electronic excitations both in TDDFT and in the Green’s function approach. The successes and failures of the different methods are presented. In particular we focused on charge-transfer excitations for which the photoexcited electron and the hole left… Read More
