Lax pair formulation for a small-polaron chain with integrable boundaries
arXiv:cond-mat/9811089 · doi:10.1002/(SICI)1521-3889(199811)7:5/6<518::AID-ANDP518>3.0.CO;2-Y
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 for the model are obtained. This provides a direct proof of the integrability of the model.
