Abstract

We investigate the correlation length of the one-dimensional S=1/2 Heisenberg antiferromagnet by the thermal Bethe-ansatz method proposed by Koma. The numerical result shows that the correlation length diverges as T-1 at low temperatures with logarithmic corrections. This logarithmic correction can be explained by conformal field theory.
