The initial Fiesta GW/Bethe-Salpeter code was written as a serial F90 version in 2010 by Xavier Blase (Institut Neel, CNRS, Grenoble). Then came the serious developers, in particular Ivan Duchemin (L_sim/INAC/CEA/Grenoble) who optimized the code, wrote the MPI parallel Fiesta version, implemented the RI-V (Coulomb metric) resolution of the identity and the "beyond Tamm-Dancoff" version of Bethe-Salpeter. Paul Boulanger , as a postdoc here in Grenoble (2013-2014), seriously consolidated the code by making, among other things, the connection with the NWChem package, opening the door to all-electron calculations with well-tested and more systematic bases (Dunning correlation consistent basis, etc.) Carina Faber, as a PhD student, performed most of the first calculations related to this project (and designed the logo we are using today on the basis of her German vision of French people). Claudio Attaccalite performed benchmark calculations with the planewave GW/BSE Yambo code. Finally, Valerio Olevano served as the wise man in the early part of this project, guiding us as Dante through the inferno of the recent developments in the field. Jing Li (postdoc, 2015-2017) and Gabriele D'Avino developed the QM/MM Fiesta fonctionality by coupling with the Mescal MM code, a discrete polarizable model with induced charges and dipoles response.
