Abstract

Integrable open-boundary condition for the q-deformed Essler–Korepin–Schoutens extended Hubbard model of strongly correlated electrons are studied in the framework of the boundary quantum inverse scattering method. Diagonal boundary K-matrices are found and nine classes of integrable boundary terms are determined.
