a Density of states (DOS) and band structure of SrNbO3 calculated by density functional theory (DFT) under compressive strain (a = 3.98 Å). The colors correspond to the orbital character of the bands. b DOS and band structure of SrVO3 calculated by DFT under tensile strain (a = 3.88 Å). The colors correspond to the orbital character of the bands. c Spectral function of SrNbO3 calculated by DFT and dynamical mean field theory (DMFT). The conduction band width W is reduced by the renormalization constant Zk compared to the DFT results in a. d Spectral function of SrVO3 calculated by DFT and DMFT. The conduction band width W is reduced by the renormalization constant Zk compared to the DFT results in b. e Schematic of the 1st Brillouin zone for tetragonally distorted SrNbO3 and SrVO3.
