摘要
Angle-resolved photoemission data from one-dimensional SrCuO₂ compounds are found to be qualitatively different from that of two-dimensional Sr₂CuO₂Cl₂. The data can be quantitatively accounted for by the exact diagonalization calculation based on the t-J model. We identify the two underlying bands having approximately 1.2 and 0.3 eV energy dispersion as that of holon and spinon, with their energy scaled by t and J, respectively.
