摘要：
As a step toward elucidating the connection between the structure and mobility of liquid water, we analyze quenched molecular dynamics configurations at different densities. We find that the mobility is directly related to the existence of "topological defects" of the tetrahedral network. The defects act as catalysts, providing lower energy pathways between different tetrahedral local arrangements.
