Full potential KKR Bloch spectral function Fermi surface maps at kz = 0.5 r.l.u. (a, b) and kz = 0.0 r.l.u. (c, d), calculated with DFT-GGA (a, c), and DFT+DMFT (U = 3.0 eV, J = 0.9 eV). b, d Changes are observed near the center of the Brillouin zone, while the square-like pockets at kz = 0.5 r.l.u. remain unaffected.
