Fig. 3: DMFT spectral function A(kx, ky, kz = 0, ω) (color bar) for undoped PNO for the 1-band model and as a function of pressure from 0 to 150 GPa at T = 0.0125t.
From: Unconventional superconductivity without doping in infinite-layer nickelates under pressure
The original DFT Wannier band and the same band renormalized with the effective mass are shown as solid white and dashed green lines, respectively.
