Quantum integrability and exact solution of the supersymmetric U model with boundary terms
Yao-Zhong Zhang, Huan-Qiang Zhou
Abstract
Quantum integrability is established for the one-dimensional supersymmetric $U$ model with boundary terms by means of the quantum inverse-scattering method. The boundary supersymmetric $U$ chain is solved by using the coordinate-space Bethe-ansatz technique and Bethe-ansatz equations are derived. This provides us with a basis for computing the finite-size corrections to the low-lying energies in the system.
