In this paper, we propose a general transformation for decorated spin models. The
advantage of this transformation is to perform a direct mapping of a decorated spin model …

The generalized decoration–iteration transformation is adapted for the exact study of a
coupled spin-electron model on 2D lattices in which localized Ising spins reside on nodal …

We study the geometrical frustration of an extended Hubbard model on a diamond chain,
