We are pleased to announce the publication of our recent paper, “Accelerating core-level GW calculations by combining the contour deformation approach with the analytic continuation of W”. This novel work introduces the CD-WAC method, combining contour deformation (CD) with an analytic continuation of the screened Coulomb interaction W, effectively reducing the scaling of CD fromContinue reading “Introducing CD-WAC: core-level GW calculations just got faster”

Participation at the Helmholtz GPU Hackathon
Our entire group, recently participated in the Helmholtz GPU Hackathon held at Forschungszentrum Jülich. Our main objective was to offload the demanding computational tasks performed by the Resolution of Identity (RI) routines in FHIaims to GPUs using CUDA. We not only succeeded in implementing GPU support within the RI routines, but we also had anContinue reading “Participation at the Helmholtz GPU Hackathon”

Publication on computation of molecular XAS spectra from BSE@GW
Check out our paper in JCTC “All-Electron BSE@GW Method for K-Edge Core Electron Excitation Energies”, where we showed that absolute core-level transition energies from BSE@GW are in excellent agreement with experiment, with a mean average error of only 0.63 eV.
