Heterogeneities in supercooled liquids: static and dynamical aspects

Abstract

We study the static and Dynamical features of undercooled hard sphere in systems in this work. The density Functional Theory(DFT) is used to detect a new class of heterogenous structures which can be identified with the supercooled metastable states observed in the Computer Simulation studies[1]. This observation is confirmed by using different relaxation of the time-correlation functions, are also studied using the mode coupling theory. Signatures of the dynamical heterogeneities[2] are observed by evaluating the non-Gaussian corrections to the self part of the van Hove carrelation function.
