Structural evidence for the continuity of liquid and glassy water

摘要: An open question is whether the liquid and glassy phases of water are thermodynamically distinct or continuous. Here we address this using molecular dynamics simulations in comparison with neutron scattering experiments to study effect temperature pressure on local structure water. From both experiments, find that at high nearly independent temperature, remarkably similar known high-density amorphous ice (HDA). Further low pressure, appears approach experimentally-measured low-density (LDA) as decreases. These results consistent continuity between H$_2$O.
