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

Shift current from models to ab-initio


Shift current from models to ab-initio

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

New poster on: tunable SHG in 2D crystals


New poster on: tunable SHG in 2D crystals

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.
