Query: Exact Boundary Critical Exponents and Tunneling Effect in Integrable
  Models for Quantum Wires   Using the principles of the conformal quantum field theory and the finite
size corrections of the energy of the ground and various excited states, we
calculate the boundary critical exponents of single- and multicomponent Bethe
ansatz soluble models. The boundary critical exponents are given in terms of
the dressed charge matrix which has the same form as that of systems with
periodic boundary conditions and is uniquely determined by the Bethe ansatz
equations. A Luttinger liquid with open boundaries is the effective low-energy
theory of these models. As applications of the theory, the Friedel oscillations
due to the boundaries and the tunneling conductance through a barrier are also
calculated. The tunneling conductance is determined by a nonuniversal boundary
exponent which governs its power law dependence on temperature and frequency.
