Nested bethe ansatz for y(gl(n)) open spin chains with diagonal boundary conditions

S. Belliard, E. Ragoucy

In this proceeding we present the nested Bethe ansatz for open spin chains of XXX-type, with arbitrary representations (i.e. “spins”) on each site of the chain and diagonal boundary matrices (K +(u), K −(u)). The nested Bethe ansatz applies for a general K −(u), but a particular form of the K +(u) matrix. We give the eigenvalues, Bethe equations and the form of the Bethe vectors for the corresponding models. The Bethe vectors are expressed using a trace formula

Exact solution of the one-dimensional Hubbard model with arbitrary boundary magnetic fields

Yuanyuan Li, Junpeng Cao, Wen‐Li Yang +2 more

The one-dimensional Hubbard model with arbitrary boundary magnetic fields is solved exactly via the Bethe ansatz methods. With the coordinate Bethe ansatz in the charge sector, the second eigenvalue problem associated with the spin sector is constructed. It is shown that the second eigenvalue problem can be transformed into that of the inhomogeneous XXX spin chain with arbitrary boundary fields which can be solved via the off-diagonal Bethe ansatz method.

By using the fusion method, we give the spin-1 XXX chain associated with sl 2 with two arbitrary spin boundary impurities. Then the exact diagonalized Hamiltonian of this model was obtained by the means of Bethe ansatz method.
