Diagonalization of 2-D inhomogeneous model related to the Hubbard model
Ruihong Yue, Tetsuo Deguchi
Abstract
We found the eigenvalues of the transfer matrix for the 2-D inhomogeneous statistical model with twisted boundary condition by using the analytic Bethe Ansatz method. In the uniform case, the derived hamiltonian generalizes the 1-D Hubbard model with the twisted boundary. We also give the energy spectra for the derived hamiltonian.
