We study the finite-size scaling (FSS) property of the correlation ratio, theratio of the correlation functions with different distances. It is shown thatthe correlation ratio is a good estimator to determine the critical point ofthe second-order transition using the FSS analysis. The correlation ratio isespecially useful for the analysis of the Kosterlitz-Thouless (KT) transition.We also present a generalized scheme of the probability-changing clusteralgorithm, which has been recently developed by the present authors, based onthe FSS property of the correlation ratio. We investigate the two-dimensionalquantum XY model of spin 1/2 with this generalized scheme, obtaining theprecise estimate of the KT transition temperature with less numerical effort.Comment: 4 pages, RevTeX4, to appear in Phys.
