Published Apr 15, 1987• 77 citations

Abstract

A pair of Lax operators which gives a set of fundamental equations in the quantum inverse scattering method is explicitly presented for the one-dimensional Hubbard model. This provides a direct proof that the model is a completely integrable system.

Lax Pair forSU(n) Hubbard Model

Rui‐Hong Yue, Ryu Sasaki B

For one dimensional SU(n) Hubbard model, a pair of Lax operators are derived, which give a set of fundamental equations for the quantum inverse scattering method under both periodic and open boundary conditions. This provides another proof of the integrability of the model under periodic boundary condition.

Huan-Qiang Zhou

The Lax pair formulation is presented for completely integrable quantum lattice spin open chains. Specifically, the Lax pair for the one-dimensional Heisenberg XXZ open chain is explicitly constructed. Our construction provides an alternative and direct demonstration of the quantum integrability of the system.
