Exact integrability of the su ( n ) Hubbard model

  title={Exact integrability of the su ( n ) Hubbard model},
  author={Ziad Maassarani},
The bosonic su(n) Hubbard model was recently introduced. The model was shown to be integrable in one dimension by exhibiting the infinite set of conserved quantities. I derive the R-matrix and use it to show that the conserved charges commute among themselves. This new matrix is a non-additive solution of the Yang-Baxter equation. Some properties of this matrix are derived. PACS numbers: 75.10.-b, 75.10.Jm, 75.10.Lp
