In this talk I present our new results on sum/difference frequency generation in 2D material. We also discuss the possibility to tune non-linear response using static or ThZ electric fields, you can find the slides of my talk here:SumFrequencyGeneration.odp and the two reference papers here: Sum frequency generation from real-time simulations in two-dimensional crystals MN….

New lecture notes on Exciton-phonon coupling are available on my web-page. In this lecture notes I derive the exciton-phonon Hamiltonian and show some application to phonon-assisted absorption/emission, for the interested reader many references are provided:Exciton-phonon Coupling
Advanced quantum materials, and ultra-fast phenomena are new areas around which the Aix-Marseille University will train European doctoral students to their high qualification through the Marie Curie actions. This has been resolved by the European Research Executive Agency (REA) in the last call ‘MSCA Doctoral Networks’.In particular the CINaM and PIIM laboratory in Marseille will… Read More
Here you can find the tutorials and the code for the Theoretical Spectroscopy Lectures. Wave-function are already provided you do not need to generate them. The tutorials include a first example of linear response from real-time simulation and second example for the calculation of SHG. In the tutorial web-page you can also download a static-serial… Read More

The event is going to take place at the CECAM HQ in Lausanne. Please take note that in order to participate… Read More
A new tutorial on exciton-phonon coupling in Yambo is available. In this tutorial we will show how to generate exciton-phonon matrix elements and calculate phonon-assisted absorption and emission. In the last part of the tutorial the exciton-phonon matrix elements will be used to calculate exciton life-time. The tutorial is based on a preliminary version of… Read More
PhD position at CINaM/Aix-Marseille Université on Theory of High-Harmonic Generation A PhD position is available in the Theory and Numerical Simulations group at CINaM, Marseille, France (see: https://www.cinam.univ-mrs.fr/) under the supervision of Claudio Attaccalite , Aurélien Manchon and Fabienne Michelini (IM2NP). The expected start date from October/November 2023 or later. The PhD project will deal… Read More
In this talk I will discuss luminescence of mono-layer hexagonal boron nitride, taking into account exciton-phonon coupling and the role of substrate. Results are compared with recent experimental measurements.Here the ODP file.
Cette année, j’ai enfin réussi le concours de directeur de recherche du CNRS en section 3, après six tentatives.Dans cet article, je souhaite partager les différents projets de recherche et présentations que j’ai utilisés au fil des années, en espérant qu’ils puissent être utiles à d’autres candidats. Presentations: Electronic and optical properties of nano-materials (2023)… Read More
Hybrid van der Waals heterostructures made of 2D materials and organic molecules exploit the high sensitivity of 2D materials to all interfacial modifications and the inherent versatility of the organic compounds. In this study, we are interested in the quinoidal zwitterion/MoS2 hybrid system in which organic crystals are grown by epitaxy on the MoS2 surface… Read More
