"A computational
perspective on the metastable phase behavior of liquid water"
Prof. Naoki Yoshida
(Department of Chemical and Biological Engineering Princeton University)
Abstract:
The preponderance of experimental evidence
is consistent with the existence of a
metastable first-order transition between
two liquid phases in supercooled water.
Computer simulation has played a major
role in defining the frontiers of knowledge
in this area. Results from a broad range
of computational and theoretical
approaches, including molecular dynamics,
free energy calculations, the theory of
critical phenomena, density functional
theory and machine learning, support the
existence of a metastable critical point
in supercooled water.
This has important consequences for the
observed behavior of ordinary,
Stable liquid water at ambient conditions.
