Exact solution of the one-dimensional Hubbard model with arbitrary boundary magnetic fields
Yuan-Yuan Li, Junpeng Cao, Wen-Li Yang +2
The one-dimensional Hubbard model with arbitrary boundary magnetic fields is solved exactly via the Bethe ansatz methods. With the coordinate Bethe ansatz in the charge sector, the…

Exact solutions and elementary excitations in the XXZ spin chain with unparallel boundary fields
Junpeng Cao, Hai-Qing Lin, Kang-jie Shi +1
By using a set of gauge transformations, the exact solutions of the XXZ spin chain with unparallel boundary magnetic fields are derived in the framework of the algebraic Bethe ansa…
