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
