Exact bulk correlation functions in one-dimensional nonadditive hard-core mixtures

In a recent paper [Phys. Rev. E 76, 031202 (2007)], Schmidt proposed a fundamental measure density functional theory for one-dimensional nonadditive hard-rod fluid mixtures and compared its predictions for the bulk structural properties with Monte Carlo simulations. The aim of this Brief Report is to recall that the problem admits an exact solution in the bulk, which is briefly summarized in a self-contained way.
