Self-consistent GW on eigenvalues only with the Yambo code

For molecules and also for molecular solids, the G0W0 approach often gives poor results. The main reason of this failure is  the DFT  starting point. In fact local or semi-local exchange correlation functionals give a too small gap compared with the experimental one, and a single shot GW is not able to correct this error…. Read More
