Bethe-root configurations and spectral degeneracy in the open XXZ chain with degenerate boundaries

Shizhang Wu, Shu Chen, Junpeng Cao +1

We investigate the structure of Bethe-root configurations in the spin-1/2 XXZ chain with degenerate open boundaries. The physical solutions of the Bethe Ansatz equations are classi…

Integrable Stochastic Processes Associated with the $D_{2}$ Algebra

Guang-Liang Li, Xin Zhang, Junpeng Cao +2

We introduce an integrable stochastic process associated with the $D_{2}$ quantum group, which can be decomposed into two symmetric simple exclusion processes. We establish the integ…

Fusion approach for quantum integrable system associated with the $gl (1∣1)$ Lie superalgebra

Xiaotian Xu, Wuxiao Wen, Tao Yang +2

In this work we obtain the exact solution of quantum integrable system associated with the Lie superalgebra $gl (1∣1)$ , both for periodic and for generic open boundary co…
