After many years the Lumen code is back.The new version of Lumen is based on Yambo 5.3.0. You can find our new code on GitLab at: https://gitlab.com/lumen-code/ Soon we will release a stable version of the code
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.
