Off-diagonal approach to the exact solution of quantum integrable systems
Yi Qiao, Junpeng Cao, Wen-Li Yang +2
We investigate the - scheme for the anti-ferromagnetic XXX spin chain under both periodic and open boundary conditions. We propose a new parametrization of the eigenvalues of…

Exact solution of the Bose Hubbard model with unidirectional hopping
Mingchen Zheng, Yi Qiao, Yupeng Wang +2
A one-dimensional Bose Hubbard model with unidirectional hopping is shown to be exactly solvable. Applying the algebraic Bethe ansatz method, we prove the integrability of the mode…
