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…

An integrable Anderson-impurity problem embedded in the one-dimensional Hubbard model
Renjie Song, Mingchen Zheng, Junpeng Cao +1
An exactly solvable one-dimensional Hubbard model with a single Anderson impurity embedded at the boundary is constructed in the framework of the quantum inverse scattering method.…

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…
