Quasi-Exactly Solvable N-Body Spin Hamiltonians with Short-Range Interaction Potentials
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
We review some recent results on quasi-exactly solvable spin models presenting near-neighbors interactions. These systems can be understood as cyclic generalizations of the usual C…

Exchange operator formalism for N-body spin models with near-neighbors interactions
A. Enciso, F. Finkel, A. Gonzalez-Lopez +1
We present a detailed analysis of the spin models with near-neighbors interactions constructed in our previous paper [Phys. Lett. B 605 (2005) 214] by a suitable generalization of…
