R"omer %A Bill Sutherland %J Physics %D 1993 %I arXiv %X We show how conformal invariance predicts the functional form of two-point correlators in one-dimensional periodic quantum systems. Numerical evidence for this functional form in a wide class of models --- including long-ranged ones --- is given and it is shown how this may be used to significantly speed up calculations of critical exponents. %U http://arxiv.org/abs/cond-mat/9303004v1
