Generalized Integrable Boundary States in XXZ and XYZ Spin Chains
Xin Qian, Xin Zhang
We investigate integrable boundary states in the anisotropic Heisenberg chain under periodic or twisted boundary conditions, for both even and odd system lengths. Our work demonstr…
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…
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…
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…
Non-linear integral equations for the XXX spin-1/2 quantum chain with non-diagonal boundary fields
Holger Frahm, Andreas Klümper, Dennis Wagner +1
The XXX spin- Heisenberg chain with non-diagonal boundary fields represents a cornerstone model in the study of integrable systems with open boundaries. Despite its si…
