Journal of Physics A Mathematical and GeneralBoundaryK-supermatrices for the one-dimensional small-polaron open chainHuan-Qiang ZhouPublished Dec 7, 1996• 13 citationsPublisherAbstractThe Lax pair for the one-dimensional small-polaron open chain is explicitly constructed. From this the general boundary K-supermatrices are found. Our construction provides a direct demonstration for the integrability of the system.DOI10.1088/0305-4470/29/23/005
