A polychromatic correlated-site percolation problem with possible relevance to the unusual behaviour of supercooled H₂O and D₂O

Introduces a new polychromatic correlated site percolation problem, which has the novel feature that the partitioning of the sites into different species arises from a purely random process-that of random bond occupancy. A particular case of this percolation problem is shown to be of possible relevance in providing a physical mechanism which may contribute to the unusual properties displayed by liquid H 2 O and D 2 O under conditions of supercooling below the melting temperature.
