Spectrum of the transfer matrices of the spin chains associated with the Lie algebra
Guang-Liang Li, Junpeng Cao, Xiao-Tian Xu +4
We study the exact solution of quantum integrable system associated with the twist Lie algebra, where the boundary reflection matrices have non-diagonal elements thus t…
