Exactly solvable spin ladder model with degenerate ferromagnetic and singlet states

D. V. Dmitriev, V. Ya. Krivnov, A. A. Ovchinnikov

We study the spin ladder model with interactions between spins on neighboring rungs. The model Hamiltonian with the exact singlet ground state degenerated with ferromagnetic state…
