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…
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…
Exact solution of a quantum integrable system associated with the exceptional Lie algebra
Guang-Liang Li, Junpeng Cao, Pei Sun +3
A quantum integrable spin chain model associated with the exceptional Lie algebra is studied. By using the fusion technique, the closed recursive relations among the fused tr…
Exact physical quantities of the XYZ spin chain in the thermodynamic limit
Zhirong Xin, Junpeng Cao, Wen-Li Yang +1
The thermodynamic limits of the XYZ spin chain with periodic or twisted boundary conditions are studied. By using the technique of characterizing the eigenvalue of the transfer mat…
Exact solution of a two-parameter extended Bariev model
Mingchen Zheng, Xin Zhang, Junpeng Cao +2
An exactly solvable strongly correlated electron model with two independent parameters is constructed in the frame of the quantum inverse scattering method, which can be seen as a…
Surface energy and elementary excitations of the XYZ spin chain with integrable open boundary fields
Zhirong Xin, Junpeng Cao, Wen-Li Yang +1
We study the thermodynamic limit of the anisotropic XYZ spin chain with non-diagonal integrable open boundary conditions. Although the -symmetry is broken, by using the new p…
