Two-photon absorption in two-dimensional crystals


Two-photon absorption in two-dimensional crystals

In this work we combine tight-binding calculations of the two-photon transition probability with sophisticated ab-initio real-time Bethe-Salpeter simulations of the two-photon resonance third-order susceptibility. This combination is a unique feature of this work: on the one hand the tight-binding calculations allow us to identify the symmetry properties of the excitons, on the other hand the… Read More

Role of excitonic effects in nonlinear optical properties of 2D materials


Role of excitonic effects in nonlinear optical properties of 2D materials

My collaborator Myrta Grüning gave a very interesting talk about the role of excitons in non-linear optical properties of 2D materials at the OSI 2017 conference. She discusses  both second and third harmonic generation in low dimensional nanostructures. Slides of her talk are available here .

GDR-REST: second general meeting in Porquerolles


GDR-REST: second general meeting in Porquerolles

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
