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…
A convenient basis for the Izergin-Korepin model
Yi Qiao, Xin Zhang, Kun Hao +4
We propose a convenient orthogonal basis of the Hilbert space for the Izergin-Korepin model (or the quantum spin chain associated with the algebra). It is shown that…
Exact solution of the relativistic quantum Toda chain
Xin Zhang, Junpeng Cao, Wen-Li Yang +2
The relativistic quantum Toda chain model is studied with the generalized algebraic Bethe Ansatz method. By employing a set of local gauge transformations, proper local vacuum stat…
Bethe States of the integrable spin-s chain with generic open boundaries
Lijun Yang, Xin Zhang, Junpeng Cao +3
Based on the inhomogeneous T-Q relation and the associated Bethe Ansatz equations obtained via the off-diagonal Bethe Ansatz, we construct the Bethe-type eigenstates of the SU(2)-i…
Bethe ansatz for an AdS/CFT open spin chain with non-diagonal boundaries
Xin Zhang, Junpeng Cao, Shuai Cui +4
We consider the integrable open-chain transfer matrix corresponding to a Y=0 brane at one boundary, and a Y_theta=0 brane (rotated with the respect to the former by an angle theta)…
Black hole evaporation based upon a q-deformation description
Xin Zhang
A toy model based upon the -deformation description for studying the radiation spectrum of black hole is proposed. The starting point is to make an attempt to consider the space…
