Acta Physica Sinica (Overseas Edition)Solvable boson-fermion model for mixed-valence systemsXuan-Rong Ma, Liu Wu-Ming, Hongwei Zhao, Fu‐Cho PuPublished Jan 1, 1997• 0 citationsPublisherAbstractUsing the Bethe ansatz technique, the exact eigenstates of the Hamiltonian of the boson-fermion model for mixed-valence systems are constructed. The Bethe ansatz equations are obtained from the periodic boundary conditions.DOI10.1088/1004-423x/6/1/001
