CRITICAL-BEHAVIOR OF A ONE-DIMENSIONAL HUBBARD-MODEL WITH 1 SINH HOPPING/

Applying the finite-size scaling in conformal field theory, we evaluat e the correlation functions and susceptibilities of a ID Hubbard model with 1/sinh(kappa r) hopping and repulsive interaction in an external magnetic field. The error introduced in our approximation scheme shou ld be exponentially small in the thermodynamic limit. Incidentally, we provide the generalization of previous work on critical exponents to the case where the right and left Fermi velocities do not coincide.
