Established the connection to the XXZ model in the appropriate limit.

Solved the modified Yang-Baxter equations for the staggered XYZ case.

Abstract

We apply to the XYZ model the technique of construction of integrable models with staggered parameters, presented recently for the XXZ case. The solution of modified Yang-Baxter equations is found and the corresponding integrable zig-zag ladder Hamiltonian is calculated. The result is coinciding with the XXZ case in the appropriate limit.
