MARKOFFIAN SPATIAL PROCESSES AND SPATIAL CORRELATIONS BETWEEN LOCAL STRUCTURESS. Baer
Department of Physical Chemistry, The Hebrew University, Jerusalem 91904, Israel
Local structures at different points in space can be compared when they are defined in terms of a common set of parameters (local structure parameters) which may vary randomly from one point in space to another. An example of such parameters is provided by the local quasi-lattice, randomly translated and rotated in space. The spatial correlations between local quasi-lattices are derived from a spatial Fokker-Planck type theory. From these correlations one can derive the radial distribution as well as the bond orientational correlations in the liquid and non-crystalline solid. The theory is extended to include different types of local symmetries (quasi-lattices) and the spatial transition probability between them.
