摘要
The multi-tier GW+EDMFT scheme is an ab-initio method for calculating the electronic structure of correlated materials.While the approach is free from ad-hoc parameters,it requires a selection of appropriate energy windows for describing low-energy and strongly correlated physics.In this study,we test the consistency of the multi-tier description by considering different low-energy windows for a series of cubic SrXO_(3)(X=V,Cr,Mn)perovskites.
