Extended Data Fig. 5

a, ARPES-measured Fermi surface with the BZ boundary (red dashed line) and the location of the energy–momentum cut of interest (magenta dashed line). b, \(\bar{{\rm{\Gamma }}}-\bar{{\rm{X}}}-\bar{{\rm{\Gamma }}}\) high-symmetry-line energy–momentum cut. c, Second-derivative plot of b. We observe an outer and an inner hole-like band at \(\bar{{\rm{\Gamma }}}\), whereas at \(\bar{{\rm{X}}}\) we observe signatures of a single hole-like band.
