Phys. Rev. Lett. 83, 3892–3895 (1999)One-Particle Spectral Properties of 1D Mott-Hubbard InsulatorsReceived 14 April 1999; published in the issue dated 8 November 1999 We use an exact holon and spinon Landau-liquid functional, which describes the holon-spinon interactions at all scattering orders, to study correlation functions of integrable multicomponent many-particle problems showing both linear and nonlinear energy bands. Motivated by recent photoemission experiments, we consider specific cases when the dominant nonlinear band terms are quadratic and apply our results to the evaluation of the half-filling 1D Hubbard model one-particle spectral functions beyond conformal field theory. © 1999 The American Physical Society URL:
