Bethe states for the two-site Bose-Hubbard model: a binomial approach

Gilberto Santos, Changrim Ahn, Angela Foerster +1

We calculate explicitly the Bethe vectors states by the algebraic Bethe ansatz method with the $gl(2)$-invariant $R$-matrix for the two-site Bose-Hubbard model. Using a binomial ex…
