Research Abstract

By the molecular dynamics simulation on a model supercooled liquid, the longitudinal wave velocity in 2 dimension is about 12 sigma/tau and 3 dimension is about 7 sigma/tau. The longitudinal wave velocity slightly becomes high for increasing temperature. The results have been published in two international conferences although domestic conferences, and a new paper will be published in the near future.
On the other hand, the transverse wave velocity remains as a subject in future. Because the longitudinal wave generates simultaneously when I want to creat the transverse wave in a model system.
