In this talk I present our study of shift current(SC) response in twisted bi-layer(TBG) and twisted tri-layer graphene (TTG). We found that TTG as an ideal platform for the observation of a highly controllable SC conductivity in the THz/infrared frequency regime. At small angle it is possible to promotes the far-infrared THz SC up to… Read More

In this seminar I present new thoeretical and exparimental results on hexagonal-boron nitride under isotropic pressure and uni-axial strain. In particalar we focused on the changes in the optical response both absortion and emission. We show how exicton behave under these extreme conditions.The presentation can You can downloaded here: A squashed and squeezed h-BN [ODP]
The first annual meeting of the new GDR HOWDI will be held in Dourdan near Paris from May 9th to 13th 2022. It will be only on site, no live streaming is planned. The meeting is dedicated to the memory of François Ducastelle, who passed away last summer. The whole network remembers with deep affection his… Read More

The second general meeting of the GDR-REST will be held in the Porquerolles island from 22.05. to 25.05.2018. This meeting aims to bring together different communities of theoretical spectroscopy which are/were historically separated, but unified under a very precise and important subject: the excited-states spectroscopy of variety of systems (for both weakly and strongly correlated… Read More
