Two channels of scattering of Hubbard chain electrons with spin and orbital interactions (exact results)

Two channels of scattering of Hubbard chain electrons with spin and orbital interactions (exact results)

A simple way to determine the channel of scattering of the Hubbard chain electrons with additional quantum number, which means the orbital or band characteristic, is demonstrated on the integrable 1D modified Hubbard model. Exact solutions are obtained for each scattering channel of the electrons. T...
