LETTER TO THE EDITOR: New examples of solvable non-uniform spin lattices
Abstract
We propose a three-parametric extension of integrable non-uniform spin lattices in 1D. In our model, the spins are located at the equilibrium positions of particles interacting via the potential 0305-4470/30/6/005/img1, the particles being confined by some external field. The Lax representation, conserved current and special set of eigenvectors are presented in explicit form.
