THE metastable extension of the phase diagram of liquid water exhibits rich features that manifest themselves in the equilibrium properties of water. For example, the density maximum at 4 °C and the minimum in the isothermal compressibility at 46 °C are thought to reflect the presence of singularities in the behaviour of thermodynamic quantities occurring in the supercooled region1 2. The 'stability–limit conjecture'3–5 suggests that these thermodynamic anomalies arise from a single limit of… Expand
A self-consistent phase diagram for supercooled water
MANY of the low-temperature thermodynamic properties of water, such as heat capacity and isothermal compressibility, exhibit anomalous behaviour that tends to diverge in the supercooled state1,2. OnExpand
Novel Features in the Equation of State of Metastable Water
The thermodynamic properties of two commonly used water pair-potentials, ST2 and TIP4P, are calculated from molecular dynamics simulations. In particular, the properties of supercooled and stretchedExpand
Behavior of supercooled aqueous solutions stemming from hidden liquid-liquid transition in water.
TLDR
The non-conserved nature of the order parameter and the consequences of its coupling with conserved properties are elucidated and it is shown how the shape of the critical line in a solution controls the difference in concentration of the coexisting liquid phases. Expand
The existence of supercooled liquid water at 150 K
Supercooled water may offer clues to the anomalous properties of its normal liquid state. The supercooled state also shows anomalous thermodynamic and transport properties at low temperatures,,.Expand
Decompression-induced melting of ice IV and the liquid–liquid transition in water
Although liquid water has been the focus of intensive research for over 100 years, a coherent physical picture that unifies all of the known anomalies of this liquid, is still lacking. Some of theseExpand
Is there a second critical point in liquid water
The supercooled and stretched regions of the phase diagram of simulated liquid water are investigated by calculating the equation of state of the ST2 and TIP4P pair-potentials. We find that simulatedExpand
Limits of stability of the liquid phase in a lattice model with water‐like properties
Explicit study of the hydrogen bond network in water offers a microscopic approach to understanding the anomalous properties of water, while an alternate, thermodynamic approach is offered by theExpand
Propagation of the polyamorphic transition of ice and the liquid–liquid critical point
TLDR
These findings strongly suggest that the polyamorphic ice transition is discontinuous; a continuous transformation should occur uniformly over the entire sample, and imply that the liquids transform discontinuously at low temperatures and thus support the liquid–liquid critical-point theory. Expand
Metastable liquid–liquid transition in a molecular model of water
TLDR
It is shown that two metastable liquid phases and a stable crystal phase exist at the same deeply supercooled thermodynamic condition, and that the transition between the two liquids satisfies the thermodynamic criteria of a first-order transition. Expand
Two-state thermodynamics and the possibility of a liquid-liquid phase transition in supercooled TIP4P/2005 water.
TLDR
The results suggest the presence of a liquid-liquid critical point and are consistent with the existence of a LLPT in this model for the simulated length and time scales, and are compared with other popular water-like models, namely, mW and ST2, and with real water, all of which are well described by two-state thermodynamics.

Anomalies of Liquid Water
Water at low temperatures (T < 300 K) reveals a multitude of unusual physico-chemical properties, which originate from the strong directivity of the hydrogen bonds. This directivity forces theExpand
Isothermal compressibility of supercooled water and evidence for a thermodynamic singularity at −45°C
Using a capillary technique for small samples, the isothermal compressibility κ T of water has been measured to −26°C. Accelerating increases of κ T at the lower temperatures can be described by anExpand

Stability and tensile strength of liquids exhibiting density maxima
If a given liquid exhibits a density maximum anywhere in its phase diagram, thermodynamic consistency dictates that such a point cannot be isolated: a density maxima locus must necessarily exist. ForExpand
