Redistribution of spectral weight across the MIT. ARPES spectral weight along ΓY measured for different dopings and structures: a undoped Ca2RuO4 at 180 K (S-Pbca, paramagnetic); b Ca2−xPrxRuO4 with x = 0.03 at 150 K (S-Pbca, paramagnetic); c fully strained Ca2−xPrxRuO4 (x = 0.04) at 10 K (L-Pbca, metallic). We display a superposition of data acquired with left and right circular polarization; the inset in c shows a clear quasiparticle peak at k = kF (dotted line); d, e DMFT calculation for the S-Pbca and L-Pbca structure along the same cut. For details, see methods. The bottom of the xy band, which becomes visible upon enhancing the contrast in the DMFT calculation of the metallic state is indicated by a dotted line in c, e. Dark colors correspond to high intensities
