Breakdown of the Stokes–Einstein relation in supercooled water: The jump-diffusion perspective
Although water is the most ubiquitous liquid it shows many thermodynamic and dynamic
anomalies. Some of the anomalies further intensify in the supercooled regime. While many …

Local self-motion of water through the Van Hove function
We show that the self-part of the Van Hove function—the correlation function describing the
dynamics of a single molecule—of water can be determined through a high-resolution …
