Lax pair formulation for a small-polaron chain with integrable boundaries

Strongly Correlated Electrons 2017-09-27 v1

Abstract

Using a fermionic version of the Lax pair formulation, we construct an integrable small-polaron model with general open boundary conditions. The Lax pair and the boundary supermatrices K±K_{\pm} for the model are obtained. This provides a direct proof of the integrability of the model.
