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 Algebra

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

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

Tensor-Network Analysis of Root Patterns in the XXX Model with Open Boundaries

Zhouzheng Ji, Pei Sun, Xiaotian Xu +3

The string hypothesis of Bethe roots is a cornerstone in the thermodynamic analysis of quantum integrable systems, since it connects root configurations with physical quantities su…

Fusion approach for quantum integrable system associated with the 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 , both for periodic and for generic open boundary co…

Exact solution of the Izergin-Korepin Gaudin model with periodic and open boundaries

Xiaotian Xu, Pei Sun, Xin Zhang +2

We study the Izergin-Korepin Gaudin models with both periodic and open integrable boundary conditions, which describe quantum systems exhibiting novel long-range interactions. Usin…
