a–c ARPES-measured E–k cuts along the \(\overline{{\rm{M}}}-\overline{\Gamma }-\overline{{\rm{M}}}\) high-symmetry line at temperatures of 220, 80, and 18 K, respectively. d, e Temperature-dependent evolution of EDCs at \(\overline{\Gamma }\) and kx = 1.0 Å−1. f, g DFT+DMFT calculated spectral functions along the L−A–L high-symmetry line at temperatures of 58 and 290 K, respectively. d indicates Cr kagome bands. h Temperature-dependent evolution of the spectral weight, calculated using DFT+DMFT and integrated in momentum space with a Fermi–Dirac distribution.
