Query: Correlation between thermodynamic anomalies and pathways of ice
  nucleation in supercooled water   The well-known classical nucleation theory (CNT) for the free energy barrier
towards formation of a nucleus of critical size of the new stable phase within
the parent metastable phase fails to take into account the influence of other
metastable phases having density/order intermediate between the parent
metastable phase and the final stable phase. This lacuna can be more serious
than capillary approximation or spherical shape assumption made in CNT. This
issue is particularly significant in ice nucleation because liquid water shows
rich phase diagram consisting of two (high and low density) liquid phases in
supercooled state. The explanations of thermodynamic and dynamic anomalies of
supercooled water often invoke the possible influence of a liquid-liquid
transition between two metastable liquid phases. To investigate both the role
of thermodynamic anomalies and presence of distinct metastable liquid phases in
supercooled water on ice nucleation, we employ density functional theoretical
approach to find nucleation free energy barrier in different regions of phase
diagram. The theory makes a number of striking predictions, such as a dramatic
lowering of nucleation barrier due to presence of a metastable intermediate
phase and crossover in the dependence of free energy barrier on temperature
near liquid-liquid critical point. These predictions can be tested by computer
simulations as well as by controlled experiments.
