Yang, Wen-Li, Sasaki, Ryu and Zhang, Yao-Zhong (2004) Z(n) elliptic Gaudin model with open boundaries. The Journal of High Energy Physics, 9: 046-1-046-18.
The Zn elliptic Gaudin model with integrable boundaries specified by generic non-diagonal K-matrices with n+1 free boundary parameters is studied. The commuting families of Gaudin operators are diagonalized by the algebraic Bethe ansatz method. The eigenvalues and the corresponding Bethe ansatz equations are obtained.
