Abstract

We study critical properties of the one-dimensional integrable Heisenberg model and supersymmetric t - J model with two-band structure. We apply conformal field theory analysis to the Bethe-ansatz solution of these models, and compute bulk susceptibilities and critical exponents. The universal formulas obtained for critical exponents can be applied to nonintegrable spin and electron models with two-band structure.
