Abstract
An integrable model with rich ground state phases is difficult to realize. In this paper, an integrable spin ladder with pure long-range Heisenberg couplings is proposed and solved via the asymptotic Bethe ansatz method. Numerical solutions of the Bethe ansatz equation show that with the variation of the coupling range parameter α, quantum phase tran
