SU(2)xSU(2) Invariant Scattering Matrix of the Hubbard Model
Fabian H. L. Essler, Vladimir E. Korepin
We consider the one-dimensional half-filled Hubbard model. We show that the excitation spectrum is given by the scattering states of four elementary excitations, which form the fun…

Scattering Matrix and Excitation Spectrum of the Hubbard Model
Fabian H. L. Essler, Vladimir E. Korepin
We consider the one-dimensional Hubbard model at half filling. We show that both excitation spectrum and S-matrix are determined by the SO(4) symmetry of the model. The complete se…

Spectrum of Low-Lying Excitations in a Supersymmetric Extended Hubbard Model
Fabian H. L. Essler, Vladimir E. Korepin
We continue the study of the -supersymmetric extension of the Hubbard model in one dimension. We determine the excitation spectrum at zero temperature even in the sectors w…
