| contents | Using an activation mechanism reproducing facilitation, a dynamic phase transition triggered by a few active molecules was recently found in a supercooled model liquid. Prompted by this finding we investigate the presence of a similar transition in supercooled water. We find the presence of the phase transition in water despite the numerous anomalies of water, suggesting universality of the transition. The transition appears at constant temperature, being only induced by the motion of a small percentage of active molecules and the system cooperativity. We observe that cooperative motions strongly increase at the transition and do not disappear when the medium viscosity drops. An increase of temperature is needed to make the cooperative motions disappear, suggesting a connection to the kinetic energy to potential energy ratio instead of the medium viscosity. |
