Abstract
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.
