Equation of state of supercooled water from the sedimentation profile.
To study the coexistence of two liquid states of water within one simulation box, we implement an equilibrium sedimentation method--which involves applying a gravitational field to the system and measuring or calculating the resulting density profile in equilibrium. We simulate a system of particles interacting via the Stillinger-2 (ST2) potential, a model for water. We detect the coexistence of two liquid phases at low temperature.
