Query: Quantum integrability and exact solution of the supersymmetric U model
  with boundary terms   The 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.
