Abstract
After brief review of our recent simulation studies on kinetic heterogeneity in supercooled liquids, we report finite-size effects observed in computer simulations by decreasing system size from N = 104 to 103 and 108. Although no significant deviation is detected in the static pair correlation functions, it is demonstrated that the structural α relaxation in smaller systems become considerably slower than that in larger systems for temperatures below Tx at which the size of the cooperative particle motions becomes comparable to the unit cell length of the small system. Also the effects of confinements in planar walls are reported.
