Fig. 3: Dramatic changes in the band structure due to orbital-selective strong correlations.
From: A topological superconductor tuned by electronic correlations
a Evolution of the ARPES spectra as a function of the Te content near the \(\bar{\Gamma }\) point and the \(\bar{M}\) point using 21.2 eV photons. b Corresponding 2D curvature plots of the raw data in (a). c Calculated spectral functions for bulk FeTe0.5Se0.5 and FeTe with different inverse spectral weights for the dxy orbital (\({Z}_{{xy}}^{-1}\)) using the density functional theory (DFT) in combination with the embedded dynamical mean field theory (eDMFT). \({Z}_{{xy}}^{-1}\) of FeTe is tuned by the Te height (Methods).
