Weak Impacts and Relaxation Processes in Water and Other Liquids

Abstract

Fast, ultrafast, and slow relaxation processes during the disturbance of liquid systems are considered. There are two fundamentally different cases of the energy transfer to a system, in the first of which the homogeneity of the system and its initial structural-kinetic properties are preserved, whereas, in the second, heterogeneity and induced correlations of the distribution of molecules emerge because of changes in the dynamics of particles. The possibility of long relaxation times of a medium disequilibrated by an external action is substantiated. The spatial sizes of the impact footprint on locally disturbed areas determine the emergence of long relaxation times in water and other viscous liquids.
