We study the scalar and pseudoscalar condensations and the eta^prime mesoncorrelators of the two-flavor massive Schwinger model in the non-zero thetavacuum. Exploiting our new method which was developed to investigatetopological effects in the previous work, we find that the pseudoscalarcondensation is non-zero and there exists a long-range correlation of theeta^prime meson. This phenomenon is well described by the clustering property.We also find that even in theta=0 case the cancellation of the long-rangecorrelation is nontrivial and requires accurate contributions from highertopological sectors. Our results imply that the fluctuation of the``disconnected'' diagram originates from the pseudoscalar condensation in eachtopological sector.Comment: 12 pages,15 figures, one reference added, minor correction
