Exact spectrum of the XX spin chain with constrained non-diagonal boundary fields
Changqing Liu, Xiaotian Xu, Xin Zhang
We study the exact spectrum of the XX spin chain with constrained non-diagonal boundary fields, which can be analyzed by solving the associated Bethe Ansatz equations. In these equ…
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…
