Here my new presentation on “Shift current from models to ab-initio”. In this presentation I discuss our recent results on shift-current in twisted 3-layer graphene and Janus Monolayer Transition-Metal Dichalcogenides. In the first work we highlight the importance of density of state plus quantum geometric effects for the SC generaiton, while in the second we… Read More
A new poster for the general conference of the French Physical Society on: tunable second harmonic generation in 2D crystals. In this work we investigate two possible mechanisms to tune SHG in 2D crystals: 1) the breaking of inversion symmetry by an external field 2) the doping effects on the excitonic SHG response. Poster source… Read More
A new talk on the Yambo code that I gave to the 1st TIMES School is available online: “Yambo à la carte“. In this talk I present the Yambo code and its functionalities. There is also a small presentation on the command lines, all the steps from DFT to Yambo and the installation.Hereafter the slides… Read More
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
