BoundaryK-supermatrices for the one-dimensional small-polaron open chain

Abstract

The 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.

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

Xi‐Wen Guan, Uwe Grimm, Rudolf A. Römer

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.

Graded reflection equations and the one-dimensional small-polaron open chain

Huan-Qiang Zhou

The graded reflection equations are presented to describe quantum integrable lattice fermion open chains on a finite interval with independent boundary conditions on each end. Specifically, the general boundary K supermatrices are determined for the one-dimensional small-polaron open chain. The result is consistent with the system under study admitting Lax pair formulation.
