Robust analytic continuation approach to many-body GW calculations
Ivan Duchemin, Xavier Blase
The analytic continuation of the GW self-energy from the imaginary to the real energy axis is a central difficulty for approaches exploiting the favourable properties of response f…
Optical properties of graphene quantum dots: the role of chiral symmetry
Denis M. Basko, Ivan Duchemin, Xavier Blase
We analyse the electronic and optical properties of graphene quantum dots (GQD) using accurate \textit{ab initio} many-body and Bethe-Salpeter calculations. We show that most…
Separable Resolution-of-the-Identity with All-Electron Gaussian Bases: Application to Cubic-scaling RPA
Ivan Duchemin, Xavier Blase
We explore a separable resolution-of-the-identity formalism built on quadratures over limited sets of real-space points designed for all-electron calculations. Our implementation p…
Modelling the photochrome-TiO2 interface with Bethe-Salpeter and TD-DFT methods
Daniel Escudero, Ivan Duchemin, Xavier Blase +1
Hybrid organic/inorganic-semiconductor systems have important applications in both molecular electronics and in photo-responsive materials. The characterization of the interface an…
