概要
- 論文の詳細を見る
We apply the coordinate Bethe ansatz naethod to the one-dimensional Hubbard model withboundary fields. We find two integrable boundaries, that is, the boundary chemical potential andthe boundary magnetic field. In total, four possible boundary conditions are explicitly presented.Using the Bethe ansatz equations, the finite size corrections and the low-lying excitation spectrunaare evaluated.
